Question

Из двух военных лагерей вышли одновременно навстречу друг другу две роты солдат.одна рота идёт со скоростью 5км/ч,а другая со скоростью 6км\ч.какое расстояние будет между ними через 3 ч,если лагеря находятся на расстоянии 38км друг от друга?

Answer 1

5*3+6*3=33 38-33=5км между ними

Answer 2

5*3+6*3=33(км)
Ответ:33 км.

Answer 3

Problem Analysis

We have two groups of soldiers, each moving towards each other from their respective camps. The first group is moving at a speed of 5 km/h, and the second group is moving at a speed of 6 km/h. We need to find the distance between them after 3 hours, given that the camps are initially 38 km apart.

Solution

To find the distance between the two groups after 3 hours, we need to calculate the total distance covered by both groups and then subtract it from the initial distance between the camps.

Let's calculate the distance covered by each group in 3 hours:

- The first group is moving at a speed of 5 km/h. So, in 3 hours, they will cover a distance of 5 km/h * 3 h = 15 km. - The second group is moving at a speed of 6 km/h. So, in 3 hours, they will cover a distance of 6 km/h * 3 h = 18 km.

Now, let's calculate the distance between the two groups after 3 hours:

- The initial distance between the camps is 38 km. - The first group has covered a distance of 15 km. - The second group has covered a distance of 18 km.

To find the distance between the two groups after 3 hours, we subtract the total distance covered by both groups from the initial distance between the camps:

Distance between the two groups after 3 hours = Initial distance - Distance covered by the first group - Distance covered by the second group = 38 km - 15 km - 18 km = 5 km

Therefore, the distance between the two groups after 3 hours will be 5 km.

Answer

The distance between the two groups after 3 hours will be 5 km.
