Question
A train of length 287 m, running at 80 km/h, crosses
another train moving in the opposite direction at 37 km/h in 18 seconds. What is the length of the other train?Solution
Let the length of second train be l m. Now, v + v = (l + l )/t ⇒ (80 + 37) × (5/18) = (287 + l)/18 ⇒ 117 × (5/18) × 18 = 287 + l ⇒ 585 = 287 + l ⇒ l = 298 m
