Question

Расстояние между двумя населенными пунктами велосипедист двигаясь со скоростью 20 км\ч преодолевает за 4ч. За какое время это же расстояние пройдёт пешеход со скоростью 5 км\ч.

Answer 1

20*4=80 км расстояние между двумя населёнными пунктами.
80:5=16 часов потребуется пешеходу, чтобы преодолеть это расстояние.

Answer 2

Calculation of Time for Pedestrian to Cover the Same Distance

To calculate the time it takes for a pedestrian to cover the same distance, we can use the formula:

Time = Distance / Speed

Given that the cyclist covers the distance in 4 hours with a speed of 20 km/h, we can substitute these values into the formula:

Time = Distance / 20

To find the distance, we can rearrange the formula:

Distance = Time * Speed

Now we can substitute the values for the pedestrian's speed (5 km/h) and solve for the time it takes for the pedestrian to cover the same distance:

Time = Distance / 5

Let's calculate the time for the pedestrian to cover the same distance:

Time = (Distance / 20) * 5

To find the value of Distance, we can use the information given that the cyclist covers the distance in 4 hours:

Distance = 4 * 20

Substituting this value into the formula for Time:

Time = (80 / 20) * 5

Simplifying the equation:

Time = 4 * 5

Therefore, the pedestrian will cover the same distance in 20 hours.
