Every day a cyclist meets a train at a particular crossing. The road is straight before the crossing and both are travelling in the same direction. The cyclist travels with a speed of 10 kmph. One day the cyclist comes late by 25 min and meets the train 5km before the crossing. What is the speed of the train?
