Explanation:
First, we will turn 5 2/5 into an improper fraction:
5 * 5 = 25 + 2 = 27/5
So they worked for 27/5 days.
We want to divide the days worked by the distance to get the unit rate of distance per day:
![(12)/((27)/(5) ) = (12)/(1) * (5)/(27)=(60)/(27)=(20)/(9)](https://img.qammunity.org/2022/formulas/mathematics/college/oykq46m218rm3em0ncmves5fo4h28s3gm1.png)
So our answer is 2
