Lerok [7]

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!

b=a+3\\
c=a+6\\
a^2+b^2=c^2\\\\
a^2+(a+3)^2=(a+6)^2\\
a^2+a^2+6a+9=a^2+12a+36\\
a^2-6a-27=0\\
a^2-9a+3a-27=0\\
a(a-9)+3(a-9)=0\\
(a+3)(a-9)=0\\
a=-3 \vee a=9\\


The length can't be negative, so the answer is 9 cm.
