Final answer:
To find the number of laps Kyle runs when Reggie has run 10 laps, set up a proportion using their lap ratios and solve.
Step-by-step explanation:
To find the number of laps Kyle runs when Reggie has run 10 laps, we can set up a proportion using their lap ratios. Since Reggie runs 4 laps in the same time that Kyle runs 3.5 laps, the proportion would be:
4/3.5 = 10/x
To solve for x, we can cross multiply and then divide:
4x = 35
x = 35/4
x = 8.75
Therefore, when Reggie has run 10 laps, Kyle would have run approximately 8.75 laps.
