A train 250 metre long takes 25 sec to cross a man running at a speed of 9 km/hr in the direction same to that of train. What is the speed of the train?
Let the speed of the train be x Relative speed = (x - 9) km/hr ⇒ (x - 9) = (250 × 18)/(25 × 5) ⇒ (x - 9) = (4500)/(225) ⇒ x – 9 = 36 ⇒ x = 36 + 9 = 45 km/hr
