Question

Пассажирский поезд, двигаясь со скоростью 60 км/ч, проходит расстояние между двумя городами за 15 часов. За сколько часов проедет это расстояние автомобиль, если его скорость равна 90 км/ч?​

Answer 1

Ответ:

Пошаговое объяснение:

60 * 15 = 900 км расстояние между городами

900 : 90 = 10 часов будет ехать автомобиль со скоростью 90 км/ч

Answer 2

1)60*15=900(км)-расстояние
2)900:90= 10(ч)-будет ехать

Answer 3

Calculation of Time for the Car to Cover the Distance

To calculate the time it will take for the car to cover the same distance, we can use the formula:

Time = Distance / Speed

Given that the passenger train travels at a speed of 60 km/h and covers the distance between the two cities in 15 hours, we can calculate the distance using the formula:

Distance = Speed x Time

Substituting the given values, we have:

Distance = 60 km/h x 15 hours

Now, we can calculate the time it will take for the car to cover the same distance with a speed of 90 km/h.

Time = Distance / Speed

Substituting the calculated distance and the given speed, we have:

Time = (60 km/h x 15 hours) / 90 km/h

Simplifying the equation, we get:

Time = 900 km / 90 km/h

Now, we can calculate the time it will take for the car to cover the distance.

Calculation:

To calculate the time it will take for the car to cover the distance, we divide the distance by the speed:

Time = Distance / Speed

Substituting the values:

Time = 900 km / 90 km/h

Simplifying the equation:

Time = 10 hours

Therefore, it will take the car 10 hours to cover the same distance at a speed of 90 km/h.
