Question
Train X, traveling at a speed of 54 km/hr, crosses
another train Y, which is moving in the opposite direction at a speed of 90 km/hr, in 't' seconds. If the ratio of the lengths of train X and train Y is 2:1, and train X crosses a pole in 40 seconds, find the value of (t + 11).Solution
Length of train X = 40 × 54 × (5/18) = 600 m Length of train Y = (600/2) × 1 = 300 m => t = (600 + 300)/[(54 + 90) ×(5/18)] = 22.5 sec Required value = (t + 11) = 22.5 + 11 = 33.5
