Train A running at speed of 126 km/hr crosses a platform having twice the length of train in 15 sec. Train B whose length is 400m crosses same platform in 36 sec, then find the speed of train B ?
Let length of train A = x Length of platform = 2x Speed = distance/time ⇒ 126 x 5/18 = (x + 2x)/15 ⇒ x = 175 m = length of train A Length of platform = 175 x 2 = 350m For train B, Speed = distance/time ⇒ (350 + 400)/36 x (18/5) ⇒ 75 km/hr
