Given:
Time taken, t = 3 hr and 10 min
Distance covered = 14.32 km
Let's find the speed of the train.
To find the speed of the train, apply the formula:

Convert the time to hour.
Where:
1 hour = 60 minutes
Thus, we have:

To find the speed, we have:
![\text{speed}=\frac{14.32\operatorname{km}}{3.17}=4.52\operatorname{km}\text{ /h}]()
Therefore, the speed of the train is 4.52 kilometers per hour.
ANSWER:
4.52 km/h
