Answer:
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
Please provide the context of problem
Answer would be 11/4
4x - 2 - 1 = 2
4x - 2 = 2 + 1
4x - 2 = 3
4x - 2 = 9
4x = 9 + 2
4x = 11
x = 11/4
