Re: average speed math

1 mile oval
you average 60mph for the first of 2 laps
how fast must you go for the second lap to average 120mph for the two laps combined?
i apologize if this is too easy

It is 180 if you count each lap seperately and time-independently. (180+60)/2 = 120. But if you go average speed by time it is different, since you spent 1/60th of an hour clearing the first lap, and you would spend less time going round the second time. Zero seconds, actually, because you would be taking two one mile laps at 1/60th of an hour = 120 mph average speed.
