Train A running at speed of 72 km/hr crosses a platform
having twice the length of train in 18 sec. Train B whose length is 300m crosses same platform in 27 sec, then find the speed of train B ?Solution
Let length of train A = x Length of platform = 2x Speed = distance/time ⇒ 72 x 5/18 = (x + 2x)/18 ⇒ x = 120 m = length of train A Length of platform = 120 x 2 = 240m For train B, Speed = distance/time ⇒ (240 + 300)/27 x (18/5) ⇒ 72 km/hr
