Question

Велосипедист за 2 часа проехал 22 км пути. Сколько километров проедет за 5 часов автомобиль, двигающийся со скоростью, в 9 раз большей скорости велосипедиста? Тема -скорость, время, расстояние (v, t, s)

Answer 1

Надо сначала узнать сколько велосипедист проедит за час
22 поделить на 2 = 11км за
 час
потом надо узнать скорость автомобиля
11 умножить на 9=99 км - скорость автомобиля за час
потом его путь за 5 часов
99 умножить на 5=495 км- проедит автомобиль за 5 часов

Answer 2

Problem Analysis

We are given that a cyclist traveled 22 km in 2 hours. We need to find out how many kilometers a car traveling at a speed 9 times greater than the cyclist will cover in 5 hours.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's calculate the speed of the cyclist first. We know that the cyclist traveled 22 km in 2 hours. Therefore, the speed of the cyclist is:

speed of cyclist = distance / time = 22 km / 2 hours = 11 km/h.

Now, we need to find the speed of the car. We are given that the car is moving at a speed 9 times greater than the cyclist. Therefore, the speed of the car is:

speed of car = 9 × speed of cyclist = 9 × 11 km/h = 99 km/h.

Finally, we can calculate the distance covered by the car in 5 hours using the formula:

distance = speed × time = 99 km/h × 5 hours = 495 km.

Therefore, the car will cover 495 kilometers in 5 hours.

Answer

The car, moving at a speed 9 times greater than the cyclist, will cover 495 kilometers in 5 hours.
