Question

Автобус проехал расстояние 480 км за 8 ч.За сколько времени пройдет это расстояние автомобиль,скорость которого на 36 км/ч больше скорости автобуса? С какой скоростью надо ехать,что бы преодолеть это расстояние за 4 часа?

Answer 1

1)480:8=60км/ч -скорость автобуса.
2)60+36=96км/ч -скорость машины.
3)480:96=за 5 часов.
4)480:4=120км/ч -должна быть скорость.

Answer 2

Найдём скорость автобуса: 480 : 8 =60 км/ч
Скорость автомобиля : 60+36=96км/ч
Время за которое пройдёт автомобиль: 480:96=5ч
Чтобы проехать за 4 часа надо ехать со скоростью 480:4=120  км/ч
Ответ 5ч, 120 км/ч  

Answer 3

Calculation of Time for the Car to Cover 480 km

To calculate the time it takes for the car to cover a distance of 480 km, we need to compare the speeds of the car and the bus. Given that the bus covered the distance in 8 hours, we can calculate its speed using the formula:

Speed = Distance / Time

Let's calculate the speed of the bus:

Bus Speed = 480 km / 8 hours = 60 km/h.

Now, we know that the car's speed is 36 km/h faster than the bus's speed. Therefore, the car's speed is:

Car Speed = Bus Speed + 36 km/h = 60 km/h + 36 km/h = 96 km/h.

To find the time it takes for the car to cover the same distance of 480 km, we can use the formula:

Time = Distance / Speed

Substituting the values, we get:

Time = 480 km / 96 km/h = 5 hours.

Therefore, it will take the car 5 hours to cover a distance of 480 km.

Calculation of Speed to Cover 480 km in 4 Hours

To calculate the speed at which the car needs to travel to cover a distance of 480 km in 4 hours, we can use the formula:

Speed = Distance / Time

Substituting the values, we get:

Speed = 480 km / 4 hours = 120 km/h.

Therefore, the car needs to travel at a speed of 120 km/h to cover a distance of 480 km in 4 hours.
