Question
A train 480 metre long takes 32 sec to cross a man
running at a speed of 6 km/hr in the direction same to that of train. What is the speed of the train?Solution
Let the speed of the train be x Relative speed = (x - 6) km/hr ⇒ (x - 6) = (480 × 18)/(32 × 5) ⇒ (x - 6) = (8640)/(160) ⇒ x – 6 = 54 ⇒ x = 54 + 6 = 60 km/hr
