650/5=130
130-60=70км/ч скорость славы

Answer 2

Problem Analysis

Slava and Nina start from the same point and move in opposite directions. After 5 minutes, the distance between them is 650 meters. We need to find Slava's speed given that Nina is moving at a speed of 60 meters per minute.

Solution

Let's assume Slava's speed is v meters per minute.

After 5 minutes, the distance covered by Slava is 5v meters.

The total distance between Slava and Nina after 5 minutes is the sum of the distances covered by both of them:

5v + 60*5 = 650

Simplifying the equation:

5v + 300 = 650

5v = 650 - 300

5v = 350

v = 350/5

v = 70

Therefore, Slava's speed is 70 meters per minute.

Answer

Slava's speed is 70 meters per minute.
