Answer 1

Решение:
16×3=48км
90-48=42
42:3=14км/ч скорость другого всадника

Answer 2

Problem Analysis

We are given that two riders start simultaneously from two different villages towards each other. The distance between the villages is 90 km. After 3 hours, they meet each other. We need to find the speed of the second rider, given that the speed of the first rider is 16 km/h.

Solution

Let's assume the speed of the second rider is x km/h.

We can use the formula speed = distance / time to find the speed of the second rider. The distance covered by the first rider in 3 hours is 16 km/h * 3 hours = 48 km.

Since the two riders are moving towards each other, the total distance covered by both riders is equal to the distance between the villages, which is 90 km.

Therefore, the distance covered by the second rider is 90 km - 48 km = 42 km.

Now we can calculate the speed of the second rider using the formula speed = distance / time:

x km/h = 42 km / 3 hours = 14 km/h.

Therefore, the speed of the second rider is 14 km/h.

Answer

The speed of the second rider is 14 km/h.
