Problem Analysis

We have two tourist groups that start simultaneously from two different tourist bases and move towards each other. After 3 hours, they are 5 km apart. The distance between the tourist bases is 35 km. We need to find the speed of the first group, given that the speed of the second group is 5 km/h.

Solution

Let's assume the speed of the first group is v km/h.

We know that the distance covered by an object is equal to the product of its speed and time. Using this formula, we can calculate the distance covered by each group.

The distance covered by the first group in 3 hours is 3v km.

The distance covered by the second group in 3 hours is 3 * 5 = 15 km.

After 3 hours, the total distance covered by both groups is equal to the distance between the tourist bases, which is 35 km. So we can write the equation:

3v + 15 = 35

Simplifying the equation:

3v = 35 - 15

3v = 20

Dividing both sides by 3:

v = 20 / 3

Therefore, the speed of the first group is 20/3 km/h.

Answer

The speed of the first group is 20/3 km/h.

Verification

Let's verify the answer using the given information.

The distance covered by the first group in 3 hours is 3 * (20/3) = 20 km.

The distance covered by the second group in 3 hours is 3 * 5 = 15 km.

The total distance covered by both groups after 3 hours is 20 + 15 = 35 km, which is equal to the distance between the tourist bases.

Therefore, the answer is verified.
