Question

two trains are 500 miles apart when they first enter a colision course. If after, two hours the distance between them is 300 miles and one train goes 20 mph faster than the other, find the speed of the faster train

Answer 1

Answer: 60mph

Explanation:

500-300 = 200

200 = distance traveled in 2 hrs

100 = distance traveled every hour

100=2x+20, x being the slower train

80=2x

x=40

40+20 = 60, the speed of the faster train
