Answer: A) 264ft/minute
Step-by-step explanation:
1. Based on the information given in the problem, the speed of the track runner was 3 miles per hour ([tex]3\frac{mi}{h}[/tex]).
2. If you want to know the speed of the track runner in feet per minute, you need to apply the following proccedure:
[tex](3\frac{mi}{h})(\frac{5280ft}{1mi})(\frac{1h}{60min})=\frac{(3)(5280)}{60}=264\frac{ft}{min}[/tex]
3. Therefore, the answer is the option A.
