Question

Два легкові автомобілі проїхали по 360 км кожний. Перший автомобіль зазначений шлях подолав за 3 год а другий за 6 годин. У скільки разів швидкість руху першого автомобіля була більшою за швидкість руху другого?

Answer 1

Ответ:

2

Пошаговое объяснение:

360/3=120 км/ч - скорость первого автомобиля.

360/6=60 км/ч - скорость второго автомобиля.

Посчитаем во сколько раз скорость движения первого автомобиля была больше скорости движения второго:

120/60=2

Answer 2

Problem Analysis

We are given that two cars traveled a distance of 360 km each. The first car took 3 hours to cover the distance, while the second car took 6 hours. We need to determine the ratio of the speed of the first car to the speed of the second car.

Solution

To find the ratio of the speeds of the two cars, we can use the formula:

Speed = Distance / Time

Let's calculate the speeds of the two cars:

For the first car: - Distance = 360 km - Time = 3 hours

Using the formula, we can calculate the speed of the first car:

Speed of the first car = 360 km / 3 hours = 120 km/h For the second car: - Distance = 360 km - Time = 6 hours

Using the formula, we can calculate the speed of the second car:

Speed of the second car = 360 km / 6 hours = 60 km/h Now, we can find the ratio of the speed of the first car to the speed of the second car:

Ratio = Speed of the first car / Speed of the second car = 120 km/h / 60 km/h = 2

Therefore, the speed of the first car was 2 times greater than the speed of the second car.

Conclusion

The speed of the first car was 2 times greater than the speed of the second car.
