Answer:
<u>24 miles per hour</u>
Step-by-step explanation:
First we need to convert days to hours. Since there are 24 hours in one day we need to multiply 5 by 24

This gives us 120 hours. Now we need to divide the total miles by the total hours

Finally we need to round to the nearest mile per hour/ones digit. When rounding, remember if it is 4 or below you round down, and if it is 5 or about you round up.
23.775 - 5 is high so round up
23.78 - 8 is high so round up
23.8 - 8 is high so round up
24 is the final answer
