Ответ три часа

Answer 3

Problem Analysis

We have two tourist bases that are 27 km apart. Two squads set out simultaneously from each base to meet each other. The first squad moves at a speed of 4 km/h, while the second squad moves at a speed of 5 km/h. We need to determine how many hours it will take for the squads to meet.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it will take for the squads to meet.

Calculation

The distance between the two bases is 27 km.

The first squad is moving at a speed of 4 km/h, so the time it will take for them to cover the distance is:

Time for first squad = Distance / Speed = 27 km / 4 km/h = 6.75 hours

The second squad is moving at a speed of 5 km/h, so the time it will take for them to cover the distance is:

Time for second squad = Distance / Speed = 27 km / 5 km/h = 5.4 hours

Since both squads started at the same time, they will meet when their total time is equal. Therefore, the squads will meet after approximately 5.4 hours.

Answer

The two squads will meet approximately 5.4 hours after they start their journey.
