Question
Two trains of length 200m and 160m respectively are
running on parallel lines of rails. When running in the same direction the faster train passes the slower one in 36 seconds, but when they are running in opposite directions with the same speeds as earlier, they pass each other in 18 seconds. Find the speed of each train?Solution
Let the speed of the faster train and slower train is x m/sec and y m/sec When running in the same direction (x – y) × 36 = (200 + 160) = 360………….(i) When running in opposite directions (x + y) × 18 = (200 + 160) = 360………….(ii) From (i) and (ii) x = 15, y = 5
A train 180 m long passes a pole in 9 seconds. What is the speed of the train (in km/h)?
