Final answer:
To find Stacy's speed, we use the formula s=d/t. By inserting the given distance of 659 m and the time of 31 s, we find that Stacy's speed is 21.26 m/s.
Step-by-step explanation:
The student's question is related to finding the speed of a bicycle rider, Stacy, who travels a total distance of 659 meters in 31 seconds.
The variables identified are: distance (d) as 659 meters, time (t) as 31 seconds, and the speed (s) that we want to calculate.
The formula to calculate speed is s = d/t. Applying the formula, we get Stacy's speed to be 21.26 m/s. This implies that Stacy traveled at an average speed of 21.26 meters per second.
