A train passes through a station at a speed of 108 km/h. The length of the station is 120 m. The train takes 7 seconds to completely pass through the station.
Work out the length of the train.
▶️ Answer/Explanation
Solution
Ans: 90 m
Convert speed to m/s: 108 km/h = 108000 m/3600 s = 30 m/s
Total distance covered = speed × time = 30 × 7 = 210 m
Train length = total distance – station length = 210 – 120 = 90 m
