Answer 2

Problem Analysis

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

Solution

To find the time it takes for the two groups to meet, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for each group to reach the meeting point.

The first group is moving at a speed of 4 km/h. The distance they need to cover is 27 km. Using the formula, we can calculate the time it takes for the first group to reach the meeting point:

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

The second group is moving at a speed of 5 km/h. Again, the distance they need to cover is 27 km. Using the formula, we can calculate the time it takes for the second group to reach the meeting point:

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

Since both groups set out simultaneously, the time it takes for them to meet will be the same for both groups. Therefore, the two groups will meet after approximately 5.4 hours.

Answer

The two groups will meet after approximately 5.4 hours.
