Question

трактор двигаясь со скоростью 9 км/ч прошёл путь между деревнями за 2 ч.с какой скоростью должен идти пешеход чтобы преодолеть это расстояние за 3 ч?

Answer 1

1) 9*2=18(км) расстояние между деревнями

2) 18:3=6 (км/ч) скорость пешехода

Ответ: 6 км/ч

 

Answer 2

Пусть х км/ч -скорость пешехода, тогда 

3х=9*2

3х=18

х=6

Ответ: 6км/ч

 

Answer 3

Problem Analysis

We are given that a tractor traveled a distance between two villages in 2 hours at a speed of 9 km/h. We need to find the speed at which a pedestrian should walk in order to cover the same distance in 3 hours.

Solution

To find the speed at which the pedestrian should walk, we can use the formula:

Speed = Distance / Time

Let's calculate the distance traveled by the tractor first. We know that the tractor traveled for 2 hours at a speed of 9 km/h. Therefore, the distance covered by the tractor can be calculated as:

Distance = Speed x Time

Substituting the given values:

Distance = 9 km/h x 2 h = 18 km

Now, let's calculate the speed at which the pedestrian should walk to cover the same distance in 3 hours. Using the formula mentioned above:

Speed = Distance / Time

Substituting the values:

Speed = 18 km / 3 h = 6 km/h

Therefore, the pedestrian should walk at a speed of 6 km/h to cover the same distance in 3 hours.

Answer

The pedestrian should walk at a speed of 6 km/h to cover the distance between the villages in 3 hours.
