A train 275 metre long takes 30 sec to cross a man running at a speed of 3 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 + 3) km/hr ⇒ (x + 3) = (275 × 18)/(30 × 5) ⇒ (x + 3) = (4950)/(150) ⇒ x + 3 = 33 ⇒ x = 33 – 3 = 30 km/hr
