The thing that throws me off is having the time unit on the bottom. I thought when you multiply the rate by the time the units of time should cancel out.

Thanks for the explanation.. I just realized the S on the bottom is a relative term. I was interpretting S incorrectly as one second, where actually it can be any amount of seconds.. 1 Min != 60s, 1Min= s 2 min=s and so on.

I personally like the Total GMAT math. It is good at covering the fundamentals of GMAT Math. If you are already able to handle all of the OG questions in two minutes though, not sure if it is going to help that much.

I seem to be missing something. What number can you square to get two? Wouldn't that just be an approximation?

What a great thread! While basic, I like dealing with percents the way I deal with sales: If an item is 40% off, then I'm paying 60% - - so going directly for the 60% instead of the 40% then subtracting from the whole.
