1
Step-by-step explanation:
Let us consider the case of 3 numbers: x, y, and z.
Then x/x+y+z + y/x+y+z + z/x+y+z = x+y+z/x+y+z = 1
The same works also for any quantity of numbers.

y----> total miles walked by Elena
z----> total miles walked by Lin
we know that
-----> equation A
----->
------> equation B
------> equation C
Substitute equation C and equation B in equation A and solve for x




Find the value of y

Find the value of z

therefore
Jada walked 
Elena walked 
Lin walked
