To determine when A and B will meet again, we can calculate the time it takes for them to cover a combined distance equal to the circumference of the circular track.
The formula to calculate the time taken for covering a distance is:
Time = Distance / Speed
For A, the speed is 10 km/h, and for B, the speed is 8 km/h. To convert these speeds to meters per minute (m/min), we divide by 60:
A's speed = 10 km/h = (10,000 m / 60 min) = 166.67 m/min B's speed = 8 km/h = (8,000 m / 60 min) = 133.33 m/min
Let's calculate the time it takes for A and B to cover a combined distance of 1000 meters:
Time = Distance / Speed
Time = 1000 m / (A's speed + B's speed)
Time = 1000 m / (166.67 m/min + 133.33 m/min)
Time = 1000 m / 300 m/min
Time = 3.33 minutes
Therefore, A and B will meet again after approximately 3.33 minutes.
