Final answer:
The unit rate of the top running speed of a rabbit is 51.79 miles per hour.
Step-by-step explanation:
To find the unit rate of the top running speed of a rabbit in miles per hour, divide the total distance traveled by the time taken. In this case, the rabbit traveled 725 miles in 14 hours. So the unit rate is 725 miles / 14 hours = 51.79 miles per hour.
