Question

Мотоцикл проехал 370км . Первые 7ч он ехал со скоростью 40 км\ч, а остальной путь он проехал за 2ч . С какой скоростью он проехал оставшийся путь?

Answer 1

S=v*t=40*7=280 км проехал мотоциклист за первые 7 часов
370-280=90 км мотоциклист проехал с другой скоростью
v=S/t=90/2=45 км/ч скорость мотоциклиста на оставшемся участке

Answer 2

Calculation of Speed

To find the speed at which the motorcycle traveled the remaining distance, we can use the formula:

Speed = Distance / Time

Let's calculate the speed:

The motorcycle traveled a total distance of 370 km. In the first 7 hours, it traveled at a speed of 40 km/h. This means it covered a distance of 40 km/h * 7 h = 280 km.

To find the remaining distance, we subtract the distance covered in the first 7 hours from the total distance: 370 km - 280 km = 90 km.

The remaining distance of 90 km was covered in 2 hours.

Now, we can calculate the speed at which the motorcycle traveled the remaining distance:

Speed = Distance / Time = 90 km / 2 h = 45 km/h.

Therefore, the motorcycle traveled the remaining distance at a speed of 45 km/h.
