Answer:
<h3>1 1/4 miles</h3>
Step-by-step explanation:
Amount of miles ran as part of an exercise routine = 7 1/2 miles = 15/2 miles
If you run 1/2 of that distance on a hill, the distance ran on the hill will be;
= 1/2 of 15/2
= 1/2 * 15/2
= 15/4 miles
If You run down a slope for the last 1/3 of the hill, the number of miles that you run down the hill will be;
1/3 of 15/4
= 1/3 * 15/4
= 15/12
= (3*5)/(3*4)
= 5/4
Write 5/4 as a mixed fraction
5/4 = 1 1/4 miles
Therefore you ran 1 1/4 miles down the slope
