Question

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at a rate of 65 miles per hour. The westbound train travels at a rate of miles per hour. How long will it take for the two trains to be miles apart

Answer 1

It will take 1 hour and 24 minutes.

Explanation:

Given that:

Eastbound train travels at a rate of 65 miles per hour and Westbound train travels at a rate of 85 miles per hour

So speed = 65 + 85 = 150 miles per hour

Total distance = 210 miles

We have to find the time, we know that

Distance = time * speed

OR

Time = distance / speed

Time = 210/150

Time = 1.4 hours

Or it can be written as:

Time = 1 hour 24 minutes

Hope this helped :D
