1) 305+312=617 м/мин скорость сближения
2) 617*4= 2468 метров было расстояние между спортсменами

Answer 2

Problem Analysis

We are given that two athletes start running towards each other simultaneously. The first athlete runs at a speed of 305 m/min, while the second athlete runs at a speed of 312 m/min. We need to find the distance between them when they meet after 4 minutes.

Solution

To find the distance between the two athletes, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by each athlete in 4 minutes and then find the total distance between them.

1. Distance traveled by the first athlete: - Speed of the first athlete = 305 m/min - Time = 4 minutes - Distance = Speed x Time = 305 m/min x 4 min = 1220 meters

2. Distance traveled by the second athlete: - Speed of the second athlete = 312 m/min - Time = 4 minutes - Distance = Speed x Time = 312 m/min x 4 min = 1248 meters

3. Total distance between the athletes: - The first athlete traveled 1220 meters towards the second athlete. - The second athlete traveled 1248 meters towards the first athlete. - Therefore, the total distance between them is the sum of these distances: - Total distance = 1220 meters + 1248 meters = 2468 meters

Answer

The distance between the two athletes when they meet after 4 minutes is 2468 meters.
