That depends on the total distance of the race, which you
have not bothered to mention.
If the team has exactly enough runners to run the entire race,
one at a time, then the number of runners needed is ...
(3) times (the total distance of the race, in miles) .
A- they are parallel because they have equal slopes.
Given.
(1)
(2)
Re-arrange equation (2)




Multiply equation (2) by -1

(3)
Combine like terms and solve.


Divide by (2y) and solve for (y).


Substitute (y) for equation (1).



Add (8) to both sides.


Divide by (3).


Check your work.
