How to extract part of a script from the internet

Here is the page in question http://www.fuel-economy.co.uk/calc.html

I am trying to extract/copy the section Real-Life Miles Per Gallon.
Not being able to work out the formula hence need to copy it from the page.

Any advice on how to do this would be great.

Thanks.

Hi,

I have now worked out the formula.
I need to think from now on a touch.

Thanks
