The unit rate of the car is simply the average speed of the car between the two points.
The unit rate of the car is 40 miles per hour
From the diagram (see attachment), we have:
So, the unit rate is:
[tex]Rate = \frac{Distance}{Time}[/tex]
This gives
[tex]Rate = \frac{80\ miles}{2\ hours}[/tex]
Simplify the quotient
[tex]Rate = 40\ miles/hour[/tex]
Hence, the unit rate of the car is 40 miles per hour
