Final answer:
Cyclist 4 has the greatest average speed of 4.50 m/s among the four cyclists. Without specific information on distance and time, we cannot determine if a bicycle's average speed is greater than, less than, or equal to 20 km/h.
Step-by-step explanation:
To determine which cyclist traveled with the greatest average speed, we calculate the average speed for each cyclist by dividing the distance traveled by the time taken.
- Cyclist 1's average speed = 95 m / 27 s ≈ 3.52 m/s
- Cyclist 2's average speed = 87 m / 22 s ≈ 3.95 m/s
- Cyclist 3's average speed = 106 m / 26 s ≈ 4.08 m/s
- Cyclist 4's average speed = 108 m / 24 s ≈ 4.50 m/s
Therefore, Cyclist 4 traveled with the greatest average speed.
The question about whether the average speed of a bicycle is greater than, less than, or equal to 20 km/h cannot be answered without specific information about the distance traveled and the time taken for that particular situation. Thus, the correct response is (D) Not enough information provided.
