Final answer:
To determine the cyclist's average speed, divide the distance traveled by the time taken. Average speed is a scalar quantity, unlike velocity which has direction. Calculate this value for each cyclist to find who had the greatest average speed.
Step-by-step explanation:
To calculate the average speed of a bicyclist, we use the definition given in physics: average speed is distance traveled divided by the time of travel. This concept is a fundamental part of motion studies.
To find out which cyclist had the greatest average speed among the ones presented, we need to calculate the average speed for each cyclist using the formula:
average speed = distance / time
