TWO WALKERS in Software
95 TWO WALKERS ECC200 Creator In None Using Barcode drawer for Software Control to generate, create Data Matrix 2d barcode image in Software applications. ECC200 Reader In None Using Barcode reader for Software Control to read, scan read, scan image in Software applications. The simplest puzzles continue to give candidates the most trouble Most people have an intuitive reaction to the solution to this puzzle It would be wrong The following puzzle explores a very familiar theme but for some reason can be very perplexing Encoding Data Matrix 2d Barcode In C#.NET Using Barcode generation for VS .NET Control to generate, create Data Matrix image in .NET applications. Generate Data Matrix ECC200 In VS .NET Using Barcode creation for ASP.NET Control to generate, create Data Matrix image in ASP.NET applications. Sally and John start off together on a onemile walk to a nearby town John walks at a constant speed Sally s pace varies For the first half mile, Sally walks at one mile per hour faster than John For the second half mile, Sally walks one mile per hour slower than John What happened as they reached the nearby town Did they arrive at the same time, and if they didn t, who arrived first, Sally or John Paint DataMatrix In VS .NET Using Barcode generation for VS .NET Control to generate, create DataMatrix image in VS .NET applications. DataMatrix Creator In Visual Basic .NET Using Barcode generator for VS .NET Control to generate, create Data Matrix image in Visual Studio .NET applications. Hint: The math seems trivial Work it out The obvious answer is that Sally and John would arrive at the same time because the effects of Sally s variable speed exactly cancel each Code 3 Of 9 Drawer In None Using Barcode drawer for Software Control to generate, create Code 39 image in Software applications. Making Bar Code In None Using Barcode printer for Software Control to generate, create barcode image in Software applications. REASONING PUZZLES THAT REQUIRE MATH
Code 128 Generation In None Using Barcode encoder for Software Control to generate, create Code 128 Code Set B image in Software applications. Data Matrix 2d Barcode Drawer In None Using Barcode drawer for Software Control to generate, create DataMatrix image in Software applications. other out But in fact, no matter what Sally s speed is, John will always arrive first This is one candidate s reasoning that a recruiter found very compelling: When Sally walks onehalf of the distance one mile slower than John, she loses more than she gains when she walks the other half of the distance one mile per hour faster than John For example, let s say that Sally s fast speed is three miles per hour, John s constant speed is two miles per hour, and Sally s slow speed is one mile per hour Sally will cover the first half mile in 10 minutes and the second half mile in 30 minutes However, John will cover the whole distance in only 30 minutes This is because when Sally is traveling fast for half a mile, John is traveling twothirds as fast as she is, but when Sally is traveling slow for half a mile, she s only traveling onehalf as fast as John Solution: The constantspeed walker (John) will always beat the variablespeed walker (Sally) GS1  13 Encoder In None Using Barcode drawer for Software Control to generate, create GTIN  13 image in Software applications. Encode Universal Product Code Version A In None Using Barcode generator for Software Control to generate, create UPCA image in Software applications. 96 HEADWIND, TAILWIND
Draw Code 2/5 In None Using Barcode generation for Software Control to generate, create Industrial 2 of 5 image in Software applications. Bar Code Scanner In VB.NET Using Barcode Control SDK for .NET framework Control to generate, create, read, scan barcode image in Visual Studio .NET applications. This is a deceptive problem similar in design to the previous puzzle Many recruiters select this puzzle when the candidate has arrived for the interview after taking a commercial airplane flight Candidates are quick to get this puzzle wrong precisely because so many of us take airplane trips for granted and think we understand the additive concepts of speed Recruiters look for candidates who really think the puzzle through and who reject the quick solution, even if they don t get the puzzle right at the end Barcode Drawer In C# Using Barcode printer for .NET Control to generate, create bar code image in .NET applications. GTIN  12 Creation In Java Using Barcode drawer for Java Control to generate, create UPCA Supplement 2 image in Java applications. Consider a roundtrip crosscountry airplane flight, for example, from New York to Los Angeles and then back to New York How will a constant and uniform wind affect the total elapsed time of the flights relative to no wind Will a constant wind, uniform across both legs of the trip, make the total flight longer, make it shorter, or have no effect USS128 Generation In None Using Barcode encoder for Microsoft Excel Control to generate, create USS128 image in Office Excel applications. Data Matrix 2d Barcode Drawer In .NET Using Barcode printer for Reporting Service Control to generate, create Data Matrix ECC200 image in Reporting Service applications. The obvious (and wrong) answer is to conclude that the effects of the headwind and tailwind will cancel each other out In fact, wind will always add delay to the total flight An understanding of the difference between an airplane s air speed and ground speed is useful Consider the following scenario: Suppose you have an airplane that flies 100 miles per hour relative to the ground You need to make a roundtrip flight between city A and city B (200 miles) The goal is to make the trip in the shortest possible time Without a wind, the roundtrip will take 4 hours Now let s imagine a uniform wind speed of 50 miles per hour The tailwind adds 50 miles per hour to the airplane s ground speed, resulting in the plane traveling at 150 miles per hour for the outbound leg of the roundtrip It will take 1 hour and 20 minutes for the first leg The headwind subtracts 50 miles per hour from the speed of the airplane, resulting in a ground speed of 50 miles per hour It will take 4 hours for the inbound leg of the roundtrip Going with the matching headwind and tailwind will cost us an extra hour and 20 minutes For a more rigorous proof of this somewhat startling result, consider this explanation: Let s w d plane s speed wind speed distance in one direction w 2) Bar Code Printer In None Using Barcode creation for Excel Control to generate, create bar code image in Excel applications. Create EAN13 In Java Using Barcode encoder for Android Control to generate, create EAN13 image in Android applications. Wind will add time to the flight by the ratio (s 2)/(s 2 d/(s d/(s d/(s d/(s w) w) w) w) d/s d/(s d/(s d/s w) w) time to complete leg flying with the wind time to complete leg flying against the wind roundtrip time ratio of flying with wind to flying with no wind
