A bus passes two bridges of length 500 m and 325 m in 90 seconds and 60 seconds respectively. The length (in m) of the bus is
As we know, Speed = distance/time Let the length of the train be x m, As we know, speed is same, then (500 + x)/90 = (325 + x)/60 ⇒ 2 (500 + x) = 3 (325 + x) ⇒ 1000 + 2x = 975 + 3x ⇒ x = 25 ∴ Length of the train is 25 m.
