Find the unit rate for 306 miles in 10 hours.
306 mi / 10 hr = 30.6 mi/hr
To find the unit rate, divide the number of miles by the number of hours.
Unit rate = total miles / total hours
Unit rate = 306 miles / 10 hours
Unit rate = 30.6 miles per hour
To find the unit rate, divide the total distance by the total time. In this case, since the total distance is 306 miles and the total time is 10 hours, divide 306 by 10:
306 miles รท 10 hours = 30.6 miles per hour
Therefore, the unit rate for 306 miles in 10 hours is 30.6 miles per hour.
