Answer:
<u>8 minutes</u>
Step-by-step explanation:
Jill jogs 3/4 of a mile in 1/10 hour.
⇒ 3/4 of a mile takes <u>6 minutes</u>
<u />
For one mile :
- 3/4 mile x 4/3 : 6 x 4/3 minutes
- 1 mile : 2 x 4 minutes
- 1 mile takes <u>8 minutes</u>
-x + 1/2 = x + 4 1/2
+x +x
1/2 = 2x + 4 1/2
-4 1/2 - 4 1/2
-4 = 2x
x = -2
