Answer:
[tex]628.5ft[/tex]
Step-by-step explanation:
Find the velocity of Tim and Stan, by dividing the distance between the time:
[tex]v_T=\frac{5280}{7} =754.3 ft/min[/tex]
[tex]v_S=\frac{5280}{6} =880ft/min[/tex]
The distance that Stan and Tim travel in 5 minutes is equal to their respective velocity multiplied by the time.
[tex]d_T=754.3\times5=3771.5ft\\[/tex]
[tex]d_S=880\times5=4400ft[/tex]
The answer to the question is the difference in miles traveled by Stan minus those traveled by Tim.
[tex]R=4400-3771.5=628.5ft[/tex]
