Problema Solution
Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at miles per hour. The eastbound train travels at miles per hour. How long will it take for the two trains to be miles apart?
Answer provided by our tutors
Let t represent the time it takes for trains to be 378mi apart
D = r*t
95t + 115t = 378
210t = 378mi
t = 378/210 = 1.8hr,time it takes for trains to be 378mi apart
