Problema Solution
An eastbound train and a westbound train meet each other on parallel tracks heading in opposite directions. The eastbound train travels 4 miles per hour faster than the westbound train. After 2.5 hours, they are 360 miles apart. At what speeds are the two trains traveling?
The eastbound train is traveling_____mph.
The westbound train is traveling_____mph.
Answer provided by our tutors
distance = speed * rate
let 'v' represent the speed of the westbound train, then 'v+4' represents the speed of the eastbound train
after meeting, they are travelling in opposite directions away from each other and their relative speed is their combined speed, hence we have:
360 = (v + v+4)2.5
solving for 'v' we have v= 70
70+4=74
the westbound train is travelling at 70 mph, the westbound train is travelling at 74 mph
