1. I used t = 12.04s and came out with 105.7m, would this still get the marks?

You should still get the marks tbh
Maybe drop one at the most but I don't see why they won't give you the marks.
3. you know that t(6 marks). too vague. How exactly did you find the time by using velocity vectors

I've attached some solutions to the MS.
There are two methods I know of so far,
Method 1 - scalar multiples, find k and therefore solve for t
Method 2 - equal gradients therefore Velocity vector A (J/I) = Velocity vector B (J/i)
And solve for t.
