Answer:
The correct answer is B. 40 mph
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Distance (d) the car traveled = 120 miles
Time (t) of the travel = 3 hours
2. What is the average rate of speed?
Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel
Replacing with the real values, we have:
Rate of speed (r) = 120/3 miles per hour
Rate of speed (r) = 40 miles per hour
The correct answer is B. 40 mph
