Hi,

I have just sumitted a maths paper and one question has given me sleepless nights and I'm after advice:

The question:

Show that x = v_{1 }+ 1/2 at^{2 }if v_{2}= v_{1 }+ at and x = (v_{1 }+ v_{2}) t-----------2

I hadn't got a clue where to even start and made a complete hash of it!

Any advice where I should of started or what I should of done would be great.

Thanks
