The distance travelled by each train is equal to its speed in miles per hour multiplied by the time travelled in hours. Since there are 60 minutes per hour, 90 minutes = 90/60 = 1.5 hours. Since no directions are given, presumably the trains are traveling in the same direction or in opposite directions. The distance between the trains will be 1.5(60 - 50) if the trains are traveling in the same direction and 1.5(60 + 50) if the trains are traveling in opposite directions. These values are 15 miles and 165 miles respectively.

If theres two trains leaving at the same time one going 60 miles per hour one going 50 miles per hour in 90 minutes how far apart will they be?
To do this you need to find out how far the trains will have gone after 90 minutes. The first train (60 x 1.5) = 90 miles The second train (50 x 1.5) = 75 miles If they were going in the same direction then they will be (90-75) miles apart: 15 miles. If they were going in opposite directions then they will be (90+75) miles apart: 165 miles.
