    It took Ariella 3 hours to hours to Ariella to arrive at the store

    Answer:

    14 mph

    Explanation:

    Average speed/rate is given by dividing the total distance covered by the total time consumed.

    Total time = 2+3=5 hours

    Total distance = 40+30 = 70 miles

    Speed = distance/time

    Speed=70/5 = 14 mph
