Поезд прошел 0,4а
Осталось 0,6а
Чтобы пройти за 5 часов надо ехать со скоростью
0,6а/5

Answer 2

Calculation of Required Speed

To determine the speed at which the train should travel to cover the remaining distance in 5 hours, we need to first calculate the total distance the train needs to travel.

Given: - The train has already covered 40% of the total distance. - The remaining distance needs to be covered in 5 hours.

Let's assume the total distance the train needs to travel is D kilometers.

According to the given information, the train has already covered 40% of the total distance, which is equal to 0.4D kilometers.

Therefore, the remaining distance is equal to 100% - 40% = 60% of the total distance, which is equal to 0.6D kilometers.

To calculate the required speed, we can use the formula:

Speed = Distance / Time

In this case, the distance is 0.6D kilometers and the time is 5 hours.

Therefore, the required speed at which the train should travel to cover the remaining distance in 5 hours is:

Speed = 0.6D / 5 = 0.12D kilometers per hour.

Please note that the value of D is not provided in the question, so we cannot determine the exact speed without knowing the total distance.
