Answer: [tex]97,346\ \frac{ft}{hr}[/tex]
Step-by-step explanation:
You need to make the conversion from miles to feet. Since:
[tex]1\ mi=5,280\ ft[/tex]
You get:
[tex](228\ mi)(\frac{5,280\ ft}{1\ mi})=1,203,840\ ft[/tex]
Convert 22 minutes to hours.
Since:
[tex]1\ hr=60\ min[/tex]
You get:
[tex](22\ min)(\frac{1\ hr}{60\ min})=0.3666\ hr[/tex]
Therefore, the time in hours is:
[tex]t=12\ hr+0.3666\ hr=12.3666\ hr[/tex]
Now you must use the following formula:
[tex]V=\frac{d}{t}[/tex]
Where "V" is the speed, "d" is distance and "t" is time.
You can identify that, in this case:
[tex]d=1,203,840\ ft\\\\t=12.3666\ hr[/tex]
Therefore, substituting values into the formula, you get:
[tex]V=\frac{1,203,840\ ft}{12.3666\ hr}\\\\V=97,346.07\ \frac{ft}{hr}\\\\V\approx97,346\ \frac{ft}{hr}[/tex]
