    3 miles per hour

    Step-by-step explanation:

    Jessica is walking home from a friend's house.

    After 2 minutes she is 0.8 miles from the home and after 12 minutes she is 0.3 miles away fro her house.

    Her rate will be = (change in distance) / change in time

    = (0.8-0.3) / (12-2)

    = 0.5/10

    = 0.05 miles per minute

    Now we will convert timings from minutes to hour.

    Or = 0.05*60

    = 3 miles per hour
