Question 922068: a car travels 400 miles on level terrain in the same ammount of the time it travels 160 miles on montain terrain. if the rate of the car is 30 miles per hour less in the muntain than on ground level, find it's rate on level ground and on mountain terrain Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! r rate on Level ground | Cross Multiplying to solve
400(r-30) = 160r
240r = 12000
r = 12000/240 = , rate on Level ground.
And...checking
400/50 = 160/20 = 8 hr
