lmk if u need explanation, my working is kinda scuffed cus i rushed it

when u found velocity why don't you add a +c because when t=0 doesn't velocity for Bo = 10 and velocity for din = 8?

the acceleration is 10 and 8, not the velocity. the initial velcoty for both is 0. I didn't add the +c cus it's inferred, hence why i said my working is scuffed

why does it say largest possible value of n isn't that the only possible value of n??

No. Suppose they start together (i.e. n = 0), then Din wins and crosses the finish line 6.39 seconds before Bo-Katan. So long as n < 6.39 s, Din crosses the line first.
