One mile is equivalent to 5280 feet. Therefore, 228 miles is equivalent to 1203840 feet.
(Note: 228 * 5280 = 1203840 feet)
Then 22 minutes is equivalent to 22/60 hours or 11/30 hours. Also, 11/30 is equivalent to 0.36667
Therefore, 12 hours and 22 minutes is equivalent to 12.366667 hours.
Lastly, the average rate of speed would be 1203840 feet / 12.366667 hours.
This is equivalent to 97345.5 feet per hour.
