J+M+S=64
J+J+S=64
J+J+J-8=64
3J=72
J=24
now figure M, and S
To find out how many miles each person ran, we can use algebraic equations.
Let's assume that each person ran x miles, except for one person who ran (x - 8) miles.
According to the given information, the total distance they ran is 64 miles. So, we can set up an equation:
x + x + (x - 8) = 64
Simplifying the equation, we have:
3x - 8 = 64
Adding 8 to both sides of the equation:
3x = 72
Dividing both sides of the equation by 3:
x = 24
Now, we know that each person ran 24 miles, except for one person who ran 24 - 8 = 16 miles.
Therefore, Jan, Maya, and Sara ran 24 miles each, except one person who ran 16 miles.
