Charity has 3 times as long a walk to school as michele has and the difference between the distances they walk is ½ mile. how far does each walk?

Let x be the distance walked by Michele

X= distance by Michele
3x = distance by Charity

3x-x=1/2
2x= 1/2
X = 1/4 miles

3x1/4 = 3/4 miles

Therefore, Michele walks 1/4 miles and charity walks 3/4 miles

Hope I helped :)

Answer is either b or c
