Calculating the Meeting Time for Andrey and Sergey

Andrey is riding a bike at a speed of 200 meters per minute, while Sergey is riding towards him at a speed of 80 meters per minute. The current distance between them is 1 kilometer and 400 meters.

To calculate the meeting time, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Relative Speed}} \]

First, let's convert the distance to meters: 1 kilometer = 1000 meters So, the total distance is 1000 meters + 400 meters = 1400 meters.

Andrey and Sergey are moving towards each other, so we can add their speeds to get the relative speed: 200 meters/minute + 80 meters/minute = 280 meters/minute.

Now, we can calculate the meeting time: \[ \text{Time} = \frac{1400 \text{ meters}}{280 \text{ meters/minute}} = 5 \text{ minutes} \]

Andrey and Sergey will meet in 5 minutes.
