having twice the length of train in 24 sec. Train B whose length is 800m crosses same platform in 36 sec, then find the speed of train B ?Solution
Let length of train A = x Length of platform = 2x Speed = distance/time ⇒ 144 x 5/18 = (x + 2x)/24 ⇒ x = 320 m = length of train A Length of platform = 320 x 2 = 640m For train B, Speed = distance/time ⇒ (640 + 800)/36 x (18/5) ⇒ 144 km/hr
