Step-by-step explanation:
I found this be adding 4 and 6, witch is 2.
I don't exactly get what your supposed to do but I thought it like this:
T V
3000 0
3000 4000
5000 4000
5000 8000
the last two are the final answers on how long the ran or it could be Terrel ran 5 kilometers while Victor ran 8 kilometers, but still idk what exactly your supposed to put

That's 21.
Hope this helps !
