Answer:
[tex]\frac{3}{4}[/tex] miles
Step-by-step explanation:
Total length of the trail = [tex]4\frac{1}{2}[/tex] miles = [tex]\frac{9}{2}[/tex] miles
She ran the first [tex]\frac{2}{3}[/tex] of the distance i.e.
The distance for which she ran = [tex]\frac{2}{3} \times \frac{9}{2} = 3\ miles[/tex]
Remaining distance = Total length of trail minus the distance for which she has already run = [tex]\frac{9}{2} - 3 = \frac{3}{2}[/tex] miles
Given that: After running, Annie has to walk due to steep nature of the trail, So, Annie walked for [tex]\frac{1}{2}[/tex] of the remaining distance.
The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] Remaining distance
The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] [tex]\frac{3}{2}[/tex] = [tex]\frac{3}{4}[/tex] miles
So, the answer is: [tex]\frac{3}{4}[/tex] miles
