Question 341582: Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 20 miles per hour slower than the eastbound train. If the two trains are 900 miles apart after 5 hours, what is the rate of the westbound train? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 20 miles per hour slower than the eastbound train. If the two trains are 900 miles apart after 5 hours, what is the rate of the westbound train?
..
let east bound train (A) speed =x mph
west bound train(B) speed will be x-20 mph.
..
Distance = speed * time
distance traveled by train A = 5x
distance traveled by train B = 5*(x-20)
..
5x+5(x-20)=900
5x+5x-100 =900
10x=900+100
10x=1000
x=100 mph east bound train
west bound train = 100-20=80 mph
