Sources for the time statistics please!
--> oh, so you ARE practicing CR as well. Good! Keep it up !
This problem can be done in less than 45 seconds in equation method
-- > Sooooooper!!!
in this case at least the equation method is fool proof and better than non-scientific methods
--> non-scientific???? did you mean non-conventional ? Then yes, my method was non-conventional.
Scientific????? I still did not understand how a scientific formula is used in the a Math problem? was it used in the solve-by-equation method? I may have missed that ! sorry again!
No offenses dude! But, if you're hurt because I questioned you're method of solving, then please accept my apology!
But, GMAC knows that we have a habit of starting from the "given" or the "L.H.S", and use the info to arrive at the answer.
This question, I think, is the same trap, wanting us do what we normally do.
My point was, why not take a different path and start with the numbers here and make it look like the part which has variables?
You said that it will take 45 seconds to make an eq and solve it. You surely must have done it within that time, but slow-heads like me will take more than 45 secs to solve an eq. That's how we were made by the almighty!
Anyway, we now have two methods to solve this question. Fellow forum-mates can choose their pick .
