Divide 31 by 2 and you will get 15.5
Length BC = 2. Everything in is the picture
It is 2.3/2.6/5/24
from least to greatest
There are 5280 feet in one mile.
If you have one and two-thirds of a mile, you can divide 5280 by 3, multiply it by 2, and then add it to 5280.
This will give you an answer of 8800 feet in 1 2/3 miles
