Question
A 140 m long train crosses another 260 m long train
running in the opposite direction in 15 seconds. If the shorter train crosses a pole in 14 seconds, what is the speed of longer train?Solution
Speed of the shorter train = 140/14 = 10 m/sec Let the speed of the longer train be x km/hr According to the question, ⇒ (10 + x) = (140 + 260)/15 ⇒ 10 + x = 400/15 ⇒ x = 400/15 – 10 = 250/15 ⇒ x = 50/3 x 18/5 = 60 km/hr
