if the cyclist would have left on time, then in those 20 minutes, he would have covered 4miles at a speed of 12miles/h so he would have been 1 mile before station whereas train would have been 5 miles before as it is on its normal time, so no change in its position. then, when the cyclist covers that 1 mile, the train covers 5 miles so that both of them meet at the station. thus, speed of the train = 5*speed of cyclist = 60 miles/hour
