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

Re: average speed math
 

the first lap took you 1/60th of an hour

to average 120mph for 2 mi, it must take you 2/120ths of an hour = 1/60th of an hour

=> the second lap takes 0 time

=> the second lap is taken at infinite speed.

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.

Yes. It's all about the post count.
