DAY 345

Haretown and Tortoiseville are 27 miles apart. The hare can run 7 mph and the tortoise can walk 2 mph. If they both start out together from their respective homes and run/walk toward each other, how many miles will the hare have traveled when they meet?

Answer:

21 miles ............ The hare and the tortoise are moving toward each other at a combined speed of 9 mph (7+2). It will take 3 hours for both of them to cover the 27 miles (27/9 = 3). In 3 hours the hare will have run 21 miles, and the tortoise will have walked 6 miles.
