A train 300 metre long takes 30 sec to cross a man running at a speed of 6 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 + 6) km/hr ⇒ (x + 6) = (300 × 18)/(30 × 5) ⇒ (x + 6) = (5400)/(150) ⇒ x + 6 = 36 ⇒ x = 36 – 6 = 30 km/hr
