Answer: [tex]\displaystyle \frac{12.075\, miles}{1 \frac{1}{6} \, hours}[/tex]
Step-by-step explanation:
First, we will find out many miles he ran.
63,756 / 5,280 = 12.075 miles
Now, we will find how many hours he ran for.
70 minutes / 60 = 1 \frac{1}{6}
"Miles per hour" will mean miles "over" hours;
[tex]\displaystyle \frac{12.075\, miles}{1 \frac{1}{6} \, hours}[/tex]
