    Answer:

    30 miles/hour, and 2.24 miles/hour

    Explanation:

    What is average speed?

    It is the total distance traveled divided by the time taken to cover the total distance traveled

    Given that the various distances are

    20 miles and 10 miles

    the total distance traveled is 20+10= 30 miles

    the average speed is expressed as

    average speed= total distance/time taken

    average speed= 30/1

    average speed= 30 miles/hour

    The average velocity is a vector quantity

    the velocity is the average displacement divided by time taken

    displacement= \sqrt{1^2+2^2} \\\\displacement= \sqrt{1+4} \\\\displacement=2.24 miles

    average velocity= displacement / time

    average velocity= 2.24 /1

    average velocity= 2.24 miles/hour
