Answer as an improper fraction = 30/8 miles
Answer as a mixed number = 3 & 3/4 miles
Answer in decimal form = 3.75 miles
============================================================
How to get that answer:
Let's start with what we're given
- length = 1/6 miles
- width = w, some unknown positive number
- area = 5/8 square miles
Assuming this site is a rectangle, then we can say:
area = length*width
5/8 = (1/6)*w
(5/8)*(6/1) = w
(5*6)/(8*1) = w
30/8 = w
w = 30/8
The answer as an improper fraction is 30/8 miles.
If you want to convert that to a mixed number, then,
30/8 = (24+6)/8
30/8 = 24/8 + 6/8
30/8 = 3 + 3/4
30/8 = 3 & 3/4
The answer as a mixed number is 3 & 3/4 miles
Meaning the width is a full 3 miles wide, plus an additional 3/4 of a mile as well.
In decimal form, the answer is 3.75 miles
