Answer 2

Calculating the Meeting Time for Two Players on a Track

To calculate the time it takes for two players to meet on a 400-meter track, we can use the concept of relative speed. The relative speed is the combined speed at which the two players are approaching each other.

Given: - Distance = 400 meters - Speed of the first player = 50 m/min - Speed of the second player = 30 m/min

Calculating Relative Speed

The relative speed of the two players is the sum of their individual speeds, as they are moving towards each other.

Relative speed = Speed of first player + Speed of second player

Relative speed = 50 m/min + 30 m/min Relative speed = 80 m/min

Calculating Meeting Time

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

Time = \(\frac{400 \text{ meters}}{80 \text{ m/min}}\)

Time = 5 minutes

Therefore, the two players will meet after 5 minutes.
