Hi

ive had a look for some of these equations on here and cant find them so i thought i would put some of them on, i find them useful ;)

SPEED EQUATIONS

Speed = Distance / Time

Transposition of this formula is:

Distance = Speed x Time

and

Time = Distance / Speed


FUEL EQUATIONS

MPG = Fuek used / miles covered



1 UK gallon = 4.545 Litres

1 litre = 0.22 UK gallons




d+((Wx(P/100)) x Pi

d = Wheel Diameter (2r)
w = Tyre width (first number on the size code)
p = Tyre Profile (second number on tyre code
Pi = Pi which is roughly 3.1



i hope everyone finds these useful and more are added as im sure there are others. ;)

cheers

Your MPG figures are all wrong:

MPG = distance / fuel used

Work out the others from there.

Also, your tyre circumfrance is all wrong. But I have dinner now, so I'll have to eat that before I can work out the correct equation. For now use:

d+((Wx(P/100)) x Pi

d = Wheel Diameter (2r)
w = Tyre width (first number on the size code)
p = Tyre Profile (second number on tyre code
Pi = Pi which is roughly 3.1
