Write 171 miles in 3 hours as a unit rate
Unit rate is nothing but the speed
We know the distance formula
Distance = Speed * Time
[tex]speed = \frac{Distance}{Time}[/tex]
Given distance = 171 miles , Time = 3 hours
[tex]speed = \frac{171 miles}{3hour}=57\frac{miles}{hour}[/tex]
Unit rate is [tex]57\frac{miles}{hour}[/tex]
