Answer:
He ran 11.200 miles per hour.
Step-by-step explanation:
The amount of miles the runner ran in hours can be expressed as a ratio (fraction):
[tex]\frac{miles}{hour} =\frac{22.21875}{2.341}=\frac{11.1998}{1}[/tex]
Since the answer is 11.1998, we can round to the nearest tenth (first place after the decimal) to get 11.2 miles per hour.
