how many hours will it take until the two trains will meet?

Question

train a leaves west town and travels at 50 mph toward smithville, 330 miles away. at the same time, train b leaves smithville and travels at 60 mph toward west town. after how many hours do the two trains meet?

Answer 1

Train A moves at 50 mph and train B moves at 60 mph. The trains are heading toward each other at a combined speed of 50+60 = 110 mph.

The total distance to be covered is 330 miles.

Thus the trains will meet in 330 miles / 110 Miles/hr = 3 hr.

Check: In 3 hours train A will travel 3 x 50 = 150 miles and train B will travel 3 x 60 = 180 miles. 150+180 = 330.
