Find the unit rate.
342 mi in 6 days
The unit rate is a way to express a quantity scaled down to "per single unit" of another quantity. In this case, to find the unit rate of miles per day, you would divide the total number of miles by the number of days.
So the calculation would be:
342 miles ÷ 6 days = 57 miles per day
Therefore, the unit rate is 57 miles per day.
