To find out how many miles does each person run, we can divide the total miles by 4 as each part is equal:
14÷4
=3.5miles
Each of them have to run 3.5 miles.
To prove the answer, we can multiply it by 4 to see if it is the original distance:
3.5 x 4
=14miles
Therefore 3.5 is the answer.
Hope it helps!
