Two trains leave stations 504 miles apart at the same time and travel toward each other. one train travels at 80 miles per hour while the other travels at 100miles per hour. how long will it take for the two trains to meet?

The two trains will meet when the sum of the distances covered by the two trains is 504 miles.

distance = speed x time.

Let the time covered when they meet be x, then:

80x + 100x = 504

180x = 504

x = 504/180 = 2.8.

Therefore, the two trains will meet in 2 hours 48 mins.
