Its law of cosines just trust me.
gotchu
i had to edit it on my laptop with the marker tool so be nice ik the handwriting suckssss
i'll write the points for you here tho:
(-2,-12)
(-1,-6)
(0,-3)
(1,-1.5)
Let d be distance travelled when they are level , and t = time that nora took to get level with mason
for Nora
6 = d/t
d = 6t
for Mason
5 = d / (t + 35)
d = 5 ( t + 350
so 6t = 5(t + 35)
solve for t
If you need the steps on how to get to 48 from 12, just multiply 12x4. Idk if that's what you need lol
