Question

В 7 часов утра из москвы вышел поезд со скоростью 60км/ч в 13 часов следующего дня в том же направлении вылетел самолет со скоростью 660км/ч через сколько часов самолет догонит поезд?

Answer 1

1) 13 -7= 6ч +24= 30ч- ехал поезд
2) 30*60= 1800км
3) 660-60= 600км/ч 
4) 1800:600=3ч

Answer 2

1) 60*30=1800(км)-поезд пройдёт к моменту вылета
Х:60=(1800+х):660
Х=1800
Х=180(км)
2) 180:60=3(ч)-догонит поезд через 3 часа)

Answer 3

Calculation of the Time it Takes for the Plane to Catch up to the Train

To calculate the time it takes for the plane to catch up to the train, we need to determine the distance traveled by both the train and the plane.

Let's assume that the distance traveled by the train is D kilometers. Since the train travels at a speed of 60 km/h, the time it takes for the train to travel this distance can be calculated using the formula:

Time taken by the train = Distance / Speed

Therefore, the time taken by the train to travel distance D is:

Time taken by the train = D / 60

Now, let's calculate the distance traveled by the plane. The plane travels at a speed of 660 km/h. The time taken by the plane to travel the same distance D is:

Time taken by the plane = D / 660

Since the plane departs at 13:00 (1:00 PM) the next day, we can subtract the departure time of the train, which is 7:00 AM, to find the total time it takes for the plane to catch up to the train.

Total time = Time taken by the plane - Time taken by the train

Substituting the values, we get:

Total time = (D / 660) - (D / 60)

To find the time it takes for the plane to catch up to the train, we need to solve for D. However, we don't have enough information to determine the value of D. The problem statement does not provide any additional information about the distance traveled by the train or the plane.

Therefore, without knowing the distance traveled by the train, we cannot calculate the exact time it takes for the plane to catch up to the train.
