Answer:
6 mph
Step-by-step explanation:
Use formula

where
D = distance
r = rate
t = time
In your case,
D = 12 mi
<u>Dina:</u>
D = 12 mi
r = 8 mph
t = ?
So,

<u>Masha:</u>
D = 12 - 3 = 8 mi
r = ?
t = 1.5 hours
Then

The difference of their speeds is 1.3 mph because Andrew was walking 4.5 mph and Jill was walking 3.2mph.
