A train 300 metre long takes 20 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) = (300 × 18)/(20 × 5) ⇒ (x - 6) = (5400)/(100) ⇒ x – 6 = 54 ⇒ x = 54 + 6 = 60 km/hr
