A train starts from a station A at 8.00 am towards station B at a speed of 70 mph. At the same time another train starts from station B towards A at the speed of 80 mph. If the distance between station A and B is 200 miles, at what time the two trains will cross each other.

The time taken for both trains to meet is 1.333 hours or 80 minutes.
The distance between both the stations is 200 miles. Since both trains are coming towards each other i.e. approaching, they will meet when the sum of their distances travelled is 200 miles.
The speed of train starting from A is 70 mph while the speed of the train starting from B is 80 mph.
Using Laws of Kinematics:
Distance = speed x time
Assuming time taken to meet is t, the total distance travelled will be:
200 = (70 x t) + (80 x t)
200 = 150 x t
t = 20 / 15
t = 1.333 hours or 80 minutes
