**Dr Russ**, Wednesday, July 23, 2008 at 7:19amYou need to find the solutions for

0=-0.13d^2+d+2

How you tackel it will depend on where you are with your maths. You could graph it (e.g. use Excel), guess values and slowly get closer to the answer or use the general equation to solve a quadratic.

For the latter:

d=-1+/-(1-4x-0.13x2)^0.5/(-0.13x2)

I get approximately 9.35 metres

but check my working.
