Question

Two trains leave the station at the same time, one traveling due east, the other due west. After 46 minutes, they are 140 miles apart. If one train's speed is 20 mph more than the other train's, what are the speeds of the two trains.

Answer 1

Train A speed = x + 20

Train B = x

We know that 46 minutes is 23/30 of an hour.

Use D = rt

Take it from here.
