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

Они через 3 часа, идя друг другу на встречу с постоянной скоростью, будут на расстоянии 5 км друг от друга.

Answer 2

Problem Analysis

We have two groups of soldiers, each moving towards each other. One group is moving at a speed of 5 km/h, and the other group is moving at a speed of 6 km/h. We need to find the distance between them after 3 hours, given that the distance between the two camps is 38 km.

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 first.

The distance covered by the first group moving at a speed of 5 km/h can be calculated using the formula:

Distance = Speed × Time

Substituting the values, we get:

Distance covered by the first group = 5 km/h × 3 h = 15 km

Similarly, the distance covered by the second group moving at a speed of 6 km/h can be calculated as:

Distance covered by the second group = 6 km/h × 3 h = 18 km

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

Distance between the two groups = Initial distance - (Distance covered by the first group + Distance covered by the second group)

Substituting the values, we get:

Distance between the two groups = 38 km - (15 km + 18 km) = 38 km - 33 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.
