Question

two trains start from towns 240 mi apart and travel towards each other on parallel tracks. they pass each other 1.6 hr later. If one train travels 10 mph faster than the other, find the speed of each train ...?

Answer 1

Let the speed of one train be s.
Speed of second train is s + 10
The speeds will add since they are traveling towards one another.
Distance = speed x time
speed = distance / time
s + s + 10 = (240/1.6)
s = 70 mph
Speed of first train is 70 mph
Speed of second train is 80 mph
