Re: average speed math
Your use of algebra is way off.
The equation you need to use to express it algebraicly is time = distance / speed giving 1/60 + 1/x = 2/120 x/60 + 1 = 2x/120 2x + 120 = 2x x + 60 = x which is clearly impossible - i.e. using this basic algebra you show its not possible.

Re: average speed math
The length of the lap and time it takes to do it are not relavent.

[/ QUOTE ] this is so dumb..put in the units and you get 1= distance 1m and 60 is mph.. then you have 1m/60mph = 1/60h = time = 1 minute to do the first lap 2m/120mph = 1/60h = time so you are showing in your equation 1 minute + 1/x = 1 minute. how dumb is this. I have to say i am pretty sure that 95% of the posts here are being sarcastic, because the answer is so simple. the correct algebraic eq is (60mph + xmph)/2 = 120mph

You are from here on out only allowed to be a mathemetician and not ever ever ever an engineer.
