    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
