the question might ask show that a,b,c are colinear
i get as far as AB = nBC
then i find AB and BC but then im lost from there, how do i finish this off? or am i even doing it properly?

but u also need to show they share the same point
so in this case u just write both share point B or something
and thats colinear

just wondering, when finding average velocity over a time interval of say [0,10] (this is for vector calculus btw) is it
( v(10) - v (0) ) / (10) ?
