Answer:
1.5 miles
Step-by-step explanation:
To get the number of miles she has jogged, what we need do is to add the distance she jogged to the high school track and the distance of the tracks
We know from the question that the laps are 0.25 miles each and there are 4. The total number of miles jogged around is thus 4 * 0.25 = 1 mile
If we now add this to the former half mile, we have the following:
1 + 0.5 = 1.5 miles
