If the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour then after 5 hours they will be in the same place.
Given that the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour.
We are required to find the time after which both the trains will be in same place.
Speed is basically the distance travelled in a particular time.
Speed=Distance/Time.
Because the difference between both the train A and train B is 10 kilometers per hour so train B will cover 50 kilometers in 5 hours.
They will be at same place after 5 hours.
Hence if the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour then after 5 hours they will be in the same place.
