Answer: r = 30 / 4.5
Step-by-step explanation:
From the question, we are informed that a football player can run 30 yards in 4.5 seconds.
The equation that is used to find r the number of yards he can run in a second will be calculated as:
r = 30 / 4.5
Solving further will be:
r = 30 / 4.5
r = 6.67 yards per seconds.
