Question

гоночный автомобиль за 6 часов прошёл 720 км а легковой автомобиль за 4 часа-240 км.во сколько раз скорость гоночного автомобиля больше скорости легкового автомобиля.

Answer 1

1) 720: 6=120 (км/ч) -скорость гоночного автомобиля;
2) 240: 4=60 (км/ч) -скорость легкового автомобиля;
3) 120: 60=2 (раз) -скорость гоночного больше легкового.
Ответ: в 2 раза скорость гоночного автомобиля больше легкового

Answer 2

Calculation of Speed

To find the ratio of the speed of the racing car to the speed of the passenger car, we need to calculate the speeds of both cars first.

Given information: - The racing car traveled 720 km in 6 hours. - The passenger car traveled 240 km in 4 hours.

To calculate the speed of each car, we can use the formula:

Speed = Distance / Time

For the racing car: Speed of the racing car = 720 km / 6 hours = 120 km/h

For the passenger car: Speed of the passenger car = 240 km / 4 hours = 60 km/h

Ratio of Speeds

Now, let's calculate the ratio of the speed of the racing car to the speed of the passenger car:

Ratio = Speed of Racing Car / Speed of Passenger Car

Ratio = 120 km/h / 60 km/h = 2

Therefore, the speed of the racing car is twice the speed of the passenger car.

Please note that the above calculations are based on the given information and assumptions.
