Write the ratio as a unit rate.
286 miles in 5 and one-half hours
To find the unit rate, divide the total number of miles by the total number of hours.
286 miles ÷ 5.5 hours = 52 miles per hour
The unit rate is 52 miles per hour.
To express the ratio as a unit rate, you need to divide the total miles by the total hours.
The ratio of 286 miles to 5 and one-half (or 5.5) hours can be written as:
