Question

Мотоцикл движется со скоростью 72км/ч А человек 4м/с во сколько раз скорость мотоцикла больше скорости человека

Answer 1

В 5 раз
V1=72 км/ч=20 м/c
V1/V2=20/4=5 м/с

Answer 2

Calculation of Speed Ratio

To calculate the ratio of the motorcycle's speed to the person's speed, we need to convert the units to be consistent. The motorcycle is moving at a speed of 72 km/h, while the person is moving at a speed of 4 m/s.

First, let's convert the motorcycle's speed from kilometers per hour to meters per second. We can use the conversion factor of 1 km/h = 0.2778 m/s.

Motorcycle speed: 72 km/h = 72 * 0.2778 m/s = 20 m/s

Now we can calculate the speed ratio:

Speed ratio = Motorcycle speed / Person's speed = 20 m/s / 4 m/s = 5

Therefore, the speed of the motorcycle is 5 times greater than the speed of the person.
