Answer: The unit rate would be 40 mi/hr.
Step-by-step explanation:
Since we have given that
Length = 140 mi
Number of hours = 3.5 hours
We need to find the unit rate.
According to question, it becomes,
[tex]\dfrac{Length}{Number\ of\ hours}[/tex]
[tex]\dfrac{140}{3.5}\\\\=40\ mi/hr[/tex]
Hence, the unit rate would be 40 mi/hr.
