Question

От станции до дачного посёлка 3 км 600м. велосипедист преодолевает это расстояние за 20 мин а пешеход тратит в 4 раза больше времени, С какой скоростью движется пешеход? какой ответ​

Answer 1

Ответ:

45 м/мин

Пошаговое объяснение:

Расстояние (S) = 3 км 600 м

Время на велосипеде  (t₁ ) = 20 мин

Время пешком (t₂) = ? , в 4 раза больше , чем на велосипеде

Скорость пешехода ( V) = ?

Переведем км в м

1 км = 1000 м

3 км 600 м = 3 * 1000 + 600 = 3600 м

Найдем сколько требуется времени ,чтоб преодолеть расстояние пешком :

t₂= 20 * 4 =80 мин

Формула скорости :

$\displaystyle V = \frac{S}{t_{2} }$

Подставим наши значения и найдем скорость пешехода :

$\displaystyle V= \frac{3600}{80}= 45 \ m/min$

Пешеход будет двигаться со скоростью 45 м/мин

Answer 2

Calculating the Pedestrian's Speed

To calculate the speed of the pedestrian, we can use the information provided about the distance and time taken by the cyclist and the pedestrian.

Given: - Distance from the station to the dacha settlement: 3 km 600 m - Time taken by the cyclist to cover this distance: 20 minutes

First, let's convert the distance to meters for consistency: 3 km 600 m = (3 * 1000) m + 600 m = 3600 m + 600 m = 4200 m

Now, we know that the cyclist covers this distance in 20 minutes. We need to find out how much time the pedestrian takes to cover the same distance.

The pedestrian takes 4 times longer than the cyclist, so the pedestrian's time can be calculated as: 20 minutes * 4 = 80 minutes

Now that we have the time taken by the pedestrian, we can calculate the pedestrian's speed.

Calculating the Pedestrian's Speed

The pedestrian's speed can be calculated using the formula: Speed = Distance / Time

Substituting the values: Speed = 4200 m / 80 minutes

Converting the time to hours for consistency: 80 minutes = 80 / 60 hours = 1.33 hours

Now, we can calculate the pedestrian's speed: Speed = 4200 m / 1.33 hours ≈ 3157.89 m/h

So, the pedestrian's speed is approximately 3157.89 meters per hour.

Therefore, the pedestrian moves at a speed of approximately 3157.89 meters per hour.
