DAY 301

Two men starting at the same point walk in opposite directions for 4 feet. Each turns left and walks another three feet. What is the distance between them?

Answer:

10 feet

When the men turn left, one is walking "up" and one is walking "down" ------------- creating two right triangles with legs of 3 and 4 feet. This is a Pythagorean triple, so the hypotenuse of each triangle is 5 feet. The men are separated by the distance of two 5-foot hypotenuses.
