A train 270 metre long takes 36 sec to cross a man running at a speed of 4 km/hr in the direction opposite to that of train. What is the speed of the train?
Let the speed of the train be x Relative speed = (x + 4) km/hr ⇒ (x + 4) = (270 × 18)/(36 × 5) ⇒ (x + 4) = (4860)/(180) ⇒ x + 4 = 27 ⇒ x = 27 – 4 = 23 km/hr
