**Reiny**, Sunday, December 30, 2012 at 10:53pmlet the time for first trip be t hrs

then the time for the return trip is 1-t hrs

so 40t = 30(1-t)

40t = 30 - 30t

70t = 30

t = 3/7 hrs

distance = 40t = 40(3/7) = 120/7 miles

or appr 17.14 miles

looks like your answers are correct, make sure you state them in the proper way.
