Answer 1

55+75=130 км прошел за 2 часа                                                                                130:2=65 км/час средняя скорость поезда

Answer 2

Calculation of Average Speed

To find the average speed of the train over the two-hour period, we can use the formula:

Average Speed = Total Distance / Total Time

Given that the train traveled 55 km in the first hour and 75 km in the second hour, the total distance covered by the train is 55 km + 75 km = 130 km.

The total time taken is 2 hours.

Now we can calculate the average speed:

Average Speed = 130 km / 2 hours = 65 km/h

Therefore, the average speed of the train over the two-hour period is 65 km/h.
