Question
Train X, traveling at a speed of 36 km/hr, crosses
another train Y, which is moving in the opposite direction at a speed of 72 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 30 seconds, find the value of (t + 11).Solution
Length of train X = 30 × 36 × (5/18) = 300 m Length of train Y = (300/2) × 1 = 150 m => t = (300 + 150)/[(36 + 72) ×(5/18)] = 15 sec Required value = (t + 11) = 15 + 11 = 26
