Question

Расстояние между автомобилями автобусом 75 километров Автомобиль движется со скоростью 70 километров в час автобус 45 километров в час через сколько часов автомобиль догонит автобус если они будут двигаться с такой же скоростью

Answer 1

Расстояние между авто и автобусом:
Через 1 час:
75-70+45=50 км
Через 2 часа:
50-70+45=25
Через 3 часа:
25-75+45=0
Ответ: Догонит через 3 часа

Answer 2

Calculation of the Time it Takes for the Car to Catch up to the Bus

To calculate the time it takes for the car to catch up to the bus, we need to determine the relative speed between the two vehicles. The relative speed is the difference between the speeds of the car and the bus.

Given: - Distance between the car and the bus: 75 kilometers - Speed of the car: 70 kilometers per hour - Speed of the bus: 45 kilometers per hour

To find the relative speed, we subtract the speed of the bus from the speed of the car:

Relative speed = Speed of the car - Speed of the bus

Relative speed = 70 km/h - 45 km/h

Relative speed = 25 km/h.

Now, we can calculate the time it takes for the car to catch up to the bus using the formula:

Time = Distance / Relative speed

Time = 75 km / 25 km/h

Time = 3 hours.

Therefore, it will take the car 3 hours to catch up to the bus if they both continue to move at the same speeds.
