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:
- The distance between the two points is: 80 miles
- The time spent to cover this distance is: 2 hours
So, the unit rate is:
This gives
Simplify the quotient
Hence, the unit rate of the car is 40 miles per hour
