C4 urgent!! Aqa Watch

1. Ok so this is for C4 AQA January 2011 paper. The last question, question 8)b)ii) talks about a trapezium. So after completing the question I realise I have two coordinates for the point of intersection. Even the mark scheme shows that you could get two coordinates, however they chose the one for when p=5/7. Why did they chose that? They don't give a reason for rejecting p=1??

I remember doing this question, and i also didnt understand why they chose 5/7.

If you consider the points where the length will be equal there will be two points (see diagram), so as you're going from point D, you need to pick the smaller value of P as selecting P = 1 will be too far along the line L2
