oh yes I did make a mistake and I got the same t for both I and j this time, thanks

yep, you are right, thanks - ADD it to the branch side. I did try separating the i and the j so I ended up with 2 quadratics - the one for i did factorise fine, the j one didnt - I may have made a mistake obviously - did you try it, and if so, did it factorise? In order to SHOW that they...

They collide when their positions are the same, so I plugged the information for the boat into equation 1 to get an expression for d which is (2i, +j)t^2 Then I used equation 4 to get an expression for d for the branch, which is (-4i, +j)t I would need to take into account the different...
