Question

Гоночный автомобиль проехал 720 км за 6 часов,а легковой автомобиль 240 км за 4 ч.Во сколько раз больit скорость гоночного автомобиля

Answer 1

Путь S
скорость V
время t
S=V•t; V= S/t; t= S/V
Sгон.=720км
t=6ч
Vгон.=720/6= 120км/ч
Sлегк.=240км
t=4ч
Vлегк.=240/4= 60км/ч


Vгон./Vлегк.= 120/60= 2раза больше

Ответ: скорость гоночного автомобиля в 2 раза больше

Answer 2

Calculation of Speed

To determine 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.

The racing car traveled a distance of 720 km in 6 hours, while the passenger car traveled a distance of 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

To find the ratio of the speed of the racing car to the speed of the passenger car, we divide the speed of the racing car by 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 racing car is 2 times faster than the passenger car.
