3 Miles Per Hour(mph)

Explanation:

After 2 minutes Sonya is 1.4 miles from home and 10 minutes later(12minutes after leaving) she has traveled another .5 miles as she's now .9 miles from home.
Difference in time between 2 minutes after leaving and 12 minutes after leaving is 10 minutes.
(1.4 - .9 = .5) so Sonya walked .5 miles in 10 minutes.
Multiply by 6 to get miles per hour as 10 minutes times 6 equals 60 minutes or 1 hour.
So .5 times 6 equals 3 so you get: '3 Miles Per Hour'.

I am of course assuming you are solving for miles per hour.
