Question
Train A crosses Train B, which is running in the
opposite direction at a speed of 60 km/h, in 18 seconds. The ratio of the lengths of Train A to Train B is 3:2. If Train A crosses a tunnel in 24 seconds, what is the length of the tunnel?Solution
Length of train A = 3x Length of train B = 2x Speed of train A = y 5x = (60 + y) * 5/18 * 18 5x = 300 + 5y We cannot find the answer.
