Question

Машина шла 3 часа со скоростью 7 километров в час а затем два часа со скоростью 8 километров час после этого осталось проехать 90 километров Какова длина пути

Answer 1

7*3 равен 21 км первая скорость 8*1 равен 8 км во второй раз скорость 21 плюс 8 равно 28 машина проехала 90 плюс 28 равно 118 км. Ответ : 118 км было расстояние пути

Answer 2

3*7=21км 2*8=16км 21+16+90=127 км общий путь

Answer 3

Calculation of the Total Distance Traveled

To calculate the total distance traveled, we need to add up the distances covered during each leg of the journey.

The car traveled at a speed of 7 kilometers per hour for 3 hours, covering a distance of 7 km/h * 3 h = 21 kilometers.

Then, the car traveled at a speed of 8 kilometers per hour for 2 hours, covering a distance of 8 km/h * 2 h = 16 kilometers.

Finally, the car had to cover a remaining distance of 90 kilometers.

Adding up the distances covered during each leg of the journey, we have:

21 kilometers + 16 kilometers + 90 kilometers = 127 kilometers.

Therefore, the total length of the path is 127 kilometers.
