Answer:
Jessica's rate is 3 miles per hour.
Step-by-step explanation:
Jessica is walking home from a friend's house.
After 2 minutes she is 1.4 miles from the home and after 12 minutes she is 0.9 miles away fro her house.
Her rate will be = [tex]\frac{\text{Change in distance}}{\text{Change in time}}[/tex]
= [tex]\frac{1.4-0.9}{12-2}[/tex]
= [tex]\frac{0.5}{10}[/tex]
= 0.05 miles per minute
Now we will convert timings from minutes to hour.
Or [tex]\frac{0.05}{\frac{1}{60}}[/tex] = 0.05×60
= 3 miles per hour
