It travels at this speed for 2 hours to reach at itsdestination. If the fault had occurred 50 miles later on, the train would have reachedits destination 45 minutes early. Find the distance traveled by the train. Let the actual speed of train be X miles/hour. after fault its speed will be reduced to 3X/5 miles/hour. If we could find the speed of the train, we will get the solution!!!by seeing one can find that
