Question

Легковая машина ехала 3ч со скоррстью 80км/ч.За сколько времени проедет это расстояние велосипедист, скорость которого в 4 раза меньше?

Answer 1

1)3*80=240(км)-расстояние которое проедет велосипедист
2)80:4=20(км/ч)- скорость велосипедиста
3)240:20=12(ч)- время за которое велосипедист преодолеет расстояние в 240 км

Answer 2

Calculation of Time for the Cyclist to Cover the Distance

To calculate the time it takes for the cyclist to cover the given distance, we need to consider the speed of the cyclist and the distance traveled by the car.

Given: - The car traveled for 3 hours at a speed of 80 km/h. - The speed of the cyclist is 4 times less than the speed of the car.

To find the time it takes for the cyclist to cover the distance, we can use the formula:

Time = Distance / Speed

Let's calculate the time for the cyclist to cover the distance.

First, let's find the distance traveled by the car:

Distance = Speed x Time

Substituting the given values: Distance = 80 km/h x 3 hours = 240 km

Now, let's find the speed of the cyclist:

Cyclist's Speed = Car's Speed / 4

Substituting the given values: Cyclist's Speed = 80 km/h / 4 = 20 km/h

Finally, let's calculate the time it takes for the cyclist to cover the distance:

Time = Distance / Speed

Substituting the values: Time = 240 km / 20 km/h = 12 hours

Therefore, it will take the cyclist 12 hours to cover the same distance that the car covered in 3 hours at a speed of 80 km/h.
