Question

Зная что автомобиль двигался со скоростью 54км/ч и проехал 216км, ответь на следующий вопрос во сколько раз уменьшиться скорость движения автомобиля, чтобы за то же время он смог проехать в 2 раза меньшее расстояние?

Answer 1

216:54=4часа-время,216:2=108км-проед.авто.,108:4=27км\ч-скорость,54:27=2раза уменьшится скорость.будут вопросы,напиши.

Answer 2

Calculation of Speed Reduction

To calculate the reduction in speed required for a car to travel a distance that is half of the original distance in the same amount of time, we can use the formula:

Speed = Distance / Time

Given that the car initially traveled at a speed of 54 km/h and covered a distance of 216 km, we can calculate the time taken using the formula:

Time = Distance / Speed

Substituting the values, we have:

Time = 216 km / 54 km/h = 4 hours

To find the reduced speed required to cover half the distance in the same time, we can use the formula:

Reduced Speed = Reduced Distance / Time

Since we want to cover half the distance, the reduced distance would be 216 km / 2 = 108 km.

Substituting the values, we have:

Reduced Speed = 108 km / 4 hours = 27 km/h

Therefore, the car would need to reduce its speed by a factor of 2 (54 km/h divided by 27 km/h) in order to cover half the distance in the same amount of time.
