Question

A freight train and an express train leave towns 390 miles apart at the same time, traveling toward one another. The freight train travels 30 mph slower than the express train. They pass one another 3 hours later. What are their speeds?

Answer 1

One train was going 80 miles the other was going 50.

Answer 2

39 mph, because 390 divided by 30 equals 13, and since they both pass 3 hours later you do 13 multiplied by 3 which is 39
