Write a unit rate for the situation.

270 miles in 6 hours
__miles per hour

270/6 mi/hr

45

To find the unit rate, we divide the total distance by the total time.

In this case, the total distance is 270 miles and the total time is 6 hours.

So, the unit rate is:

270 miles / 6 hours = 45 miles per hour

To calculate the unit rate, we need to find the number of miles per hour. The unit rate is given by the ratio of miles to hours.

To find the unit rate, we divide the total number of miles (270 miles) by the total number of hours (6 hours):

270 miles ÷ 6 hours = 45 miles per hour

Therefore, the unit rate for this situation is 45 miles per hour.
