Question

You live in a city where the East-West streets are named using letters of the alphabet and the North-South avenues are named using numbers. The streets and avenues are arranged in grids – the streets are perpendicular to the avenues. You live on F street a half mile east of 2nd Avenue. Your friend lives on the same street a half mile west of 2nd Avenue. Both of you decide to meet at the neighborhood market at the end of 2nd Avenue directly north of F street. If both of you leave your houses at the same time, who will get to the market first?

Answer 1

Let's see that between the three points you can draw an equilateral triangle since the distance between you and your friend from the second avenue is the same and the streets are perpendicular to each other (besides that they form a grid). Since both must travel the same distance and neither is supposed to be faster than the other. Your friend and you will arrive at the market at the same time.
