Answer 2

Calculation of Distance Traveled by the Train

To calculate the distance traveled by the train before making the stop at 3 a.m., we need to know the time it took for the train to reach that point. The train started at 9 p.m. and made the stop at 3 a.m., which means it traveled for a total of 6 hours.

The speed of the train is given as 72 km/h. To find the distance traveled, we can use the formula:

Distance = Speed × Time

Substituting the given values:

Distance = 72 km/h × 6 hours

Calculating the result:

Distance = 432 km

Therefore, the train traveled a distance of 432 kilometers before making the stop at 3 a.m.
