Question

An eastbound train and a westbound train meet each other on parallel tracks heading in opposite directions. The eastbound train travels 12 miles per hour faster than the westbound train. After 2 hours, they are 216 miles apart. At what speeds are the two trains traveling?

The eastbound train is traveling  ____ mph.

The westbound train is traveling ____ mph.

Answer 1

e = 12+ w

(e+w) x 2 = 216

e + w = 108

12+w + w = 108

2w = 108-12 = 96

w = 96/2 = 48 mph = westbound speed

e = 108-48 = 60 mph = eastbound speed
