A train of length 99m takes 11 seconds to pass completely through a station of length 231m. What is the speed of the train in km/h?
Explanation
Total distance:
- Length of the train: 99m
- Length of the station: 231m
- Total distance = Length of the train + Length of the station = 99m + 231m = 330m
Total time: 11 seconds
Speed:
- Speed = Distance / Time
- Speed = 330m / 11s = 30 m/s
Now, we need to convert m/s to km/h:
- 1 m/s = 3.6 km/h
So, 30 m/s = 30 * 3.6 = 108 km/h
Therefore, the speed of the train is 108 km/h.
