John walked 10 miles on Saturday. He walked twice as fast on the second 5 miles of his walk than he walked on the first 5 miles of his walk. Which expression represents the time he spent walking? Let x = John's speed on the first half of his walk.

22 answers

since time = distance/speed, we have

5/x + 5/(2x) = 15/(2x)
