running in the opposite direction in 16 seconds. If the shorter train crosses a pole in 17 seconds, what is the speed of longer train?Solution
Speed of the shorter train = 170/17 = 10 m/sec Let the speed of the longer train be x km/hr According to the question, β (10 + x) = (170 + 310)/16 β 10 + x = 480/16 β x = 30 β 10 = 20 β x = 20 x 18/5 = 72 km/hr
