Answer:
Therefore you need to walk 12 loops.
Step-by-step explanation:
Given that,
The distance walking once around the track is [tex]\frac14[/tex] miles.
To walk [tex]\frac14[/tex] mile, you need to take 1 round around the track
To walk 1 mile, you need to take [tex]\frac1{\frac14}[/tex] round around the track.
To walk 3 miles, you need to take [tex]\frac1{\frac14}\times 3[/tex] round around the track
=12 rounds.
Therefore you need to walk 12 loops.
