Question

Two trains leave stations 560 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at 110

miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.

Answer 1

Answer: the two trains will meet in 2.8 hours

Explanation:

Step 1

Speed of train A = 90mph

Speed of train B = 110 mph

Since both trains are travelling towards each other , their effective speed will be= 90 mph + 110mph= 200mph

Step 2

we know that Speed = distance / time

therefore Time = Distance / speed

Distance = 560 miles

Speed = 200 mph

Time = 560miles / 200mph

2.8 hours
