**Reiny**, Friday, April 26, 2013 at 10:58pmTime of first trip = 240/x

time of return trip = 240/(2x)

240/x - 240/2x = 5

multiply each term by 2x

480 - 240 = 10x

10x = 240

x = 24

speed on first trip was 24 mph

speed on return trip was 48 mph

check:

time for 1st trip = 240/24 = 10 hrs

time for 2nd trip - 240/48 - 5 hrs, which is 5 hrs less.
