Question

Из одного города в другой выехала машина. Весь путь она преодолела за 10 часов со скоростью 60 км ч время на обратную дорогу составило 6 часов С какой скоростью ехала машина обратно?

Answer 1

Пройденный путь равен 60 ×10=600 км S=U×t
Скорость на обратном участке пути равна 600÷6=100км/ч U=S÷t

Answer 2

Problem Analysis

We are given that a car traveled from one city to another in 10 hours at a speed of 60 km/h. We need to determine the speed of the car on the return journey, which took 6 hours.

Solution

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

Speed = Distance / Time

Let's calculate the distance traveled by the car on the outbound journey and the return journey.

On the outbound journey: - Speed = 60 km/h - Time = 10 hours

Using the formula, we can calculate the distance:

Distance = Speed * Time

Distance = 60 km/h * 10 hours = 600 km On the return journey: - Time = 6 hours

Using the formula, we can calculate the speed:

Speed = Distance / Time

Speed = 600 km / 6 hours = 100 km/h

Therefore, the speed of the car on the return journey was 100 km/h.

Conclusion

The car traveled at a speed of 100 km/h on the return journey.
