hour?
Round to the nearest hundredth

Answer 1

Answer: 39.23 miles per hour

Explanation:

1 day = 24 hour

3 days = 72 hours

Add one more hour for both to get to 9 AM, so it will take 73 hours to get there.

Now we find the average rate of change.

We take 2864 divided by 73 = 39.23 miles per hour
