Calculating Cyclist's Speed on Circular Track
The first step in calculating the cyclist's speed on a circular track is to determine the circumference of the track. Since the track's diameter is given as 105 m, we can calculate its circumference using the formula:
Circumference = π * Diameter
Circumference = π * 105 m
Circumference ≈ 3.14 * 105 m
Circumference ≈ 329.7 m

Calculating Speed
To calculate the cyclist's speed, we need to determine the distance traveled by the cyclist in 5 minutes. Since speed is defined as distance traveled divided by time taken, we can use the formula:
Speed = Distance / Time
Given that the cyclist completes one full lap around the circular track in 5 minutes, the distance traveled by the cyclist is equal to the circumference of the track. Therefore, the speed of the cyclist can be calculated as:
Speed = 329.7 m / 5 min
Speed ≈ 65.94 m/min
Therefore, the cyclist's speed on the circular track is approximately 65.94 meters per minute. This means that the cyclist covers a distance of 65.94 meters every minute while cycling around the track.
In conclusion, by calculating the circumference of the circular track and using the formula for speed, we were able to determine the cyclist's speed as approximately 65.94 meters per minute.
