$97,346\ \frac{ft}{hr}$

Step-by-step explanation:

You need to make the conversion from miles to feet. Since:

$1\ mi=5,280\ ft$

You get:

$(228\ mi)(\frac{5,280\ ft}{1\ mi})=1,203,840\ ft$

Convert 22 minutes to hours.

Since:

$1\ hr=60\ min$

You get:

$(22\ min)(\frac{1\ hr}{60\ min})=0.3666\ hr$

Therefore, the time in hours is:

$t=12\ hr+0.3666\ hr=12.3666\ hr$

Now you must use the following formula:

$V=\frac{d}{t}$

Where "V" is the speed, "d" is distance and "t" is time.

You can identify that, in this case:

$d=1,203,840\ ft\\\\t=12.3666\ hr$

Therefore, substituting values into the formula, you get:

$V=\frac{1,203,840\ ft}{12.3666\ hr}\\\\V=97,346.07\ \frac{ft}{hr}\\\\V\approx97,346\ \frac{ft}{hr}$
