Question

Расстояние между пунктами а и б -240км.расстояние между пунктами а и б -240км. на половине пути между а и б расположен пункт с. автобус проехал от а до с со скоростью 60км/ч, а от с до в со скоростью 40км/ч .автомобиль проехал от а до в за такое же время что и автобус, но с постоянной скоростью. с какой скоростью ехал автомобиль?

Answer 1

Тут деление 240 60 и умножение

Answer 2

240:2=120(км)-расстояние а-с,с-в
120:60=2(ч)
120:40=3(ч)
2+3=5(ч)-время автобуса и автомобиля
240:5=48(км/ч)-скорость автомобиля

Answer 3

Calculation of the Car's Speed

To determine the speed of the car, we need to consider the given information. Let's break it down step by step:

1. The distance between points A and B is 240 km. 2. There is a point C located halfway between points A and B. 3. The bus travels from point A to point C at a speed of 60 km/h. 4. The bus then travels from point C to point B at a speed of 40 km/h. 5. The car travels from point A to point B in the same amount of time as the bus, but at a constant speed.

To find the speed of the car, we can use the formula:

Speed = Distance / Time

Since the time taken by the bus and the car is the same, we can equate their distances:

Distance covered by the bus = Distance covered by the car

Let's calculate the distances covered by the bus and the car:

- Distance covered by the bus from A to C: (1/2) * 240 km = 120 km - Distance covered by the bus from C to B: (1/2) * 240 km = 120 km - Distance covered by the car from A to B: 240 km

Now, let's calculate the speed of the car:

Speed of the car = Distance covered by the car / Time taken by the car

Since the time taken by the car is the same as the bus, we can ignore the time factor and calculate the speed directly:

Speed of the car = Distance covered by the car / Time taken by the car = 240 km / Time taken by the car

To find the speed of the car, we need to determine the time taken by the car. Since the distances covered by the bus and the car are the same, we can equate their distances:

Distance covered by the bus = Distance covered by the car

120 km + 120 km = 240 km

Therefore, the car covers the same distance of 240 km.

Now, we can calculate the speed of the car:

Speed of the car = Distance covered by the car / Time taken by the car = 240 km / Time taken by the car

Unfortunately, the given information does not provide the exact time taken by the car. Without the time, we cannot calculate the speed of the car accurately.

Please provide the time taken by the car, and I will be able to calculate the speed for you.
