Question 395322: A long distance trucker traveled 80 miles in one direction during a snow storm. The return trip in rainy whether was accomplished at double the speed and took 2 hours less time. Find the speed going? Answer by jrfrunner(365) (Show Source):
You can put this solution on YOUR website! remember the relationship distance=rate*time or d=rt
-
going: 80 miles at speed r and time t 80=rt
coming: 80 miles at speed 2r and time t-2 80=2r*(t-2) or 40=r(t-2)=rt-2r
--
80=rt and 40=rt-2r
40=80-2r
2r=40
r=20 this is the going speed 20mph
