You can put this solution on YOUR website! Estimating :
Approximately , about a little more than halfway up from to ; those being 180 and 240.
Imagine that to be near 215, just thinking mentally, almost visually.
The exact computation:
My final estimation step was imprecise, but it was, at least, not a bad estimate, ... I could have looked at the difference from 240 to 180, which would be 60, and cut this in half, being 30, and add this to 180, to get 210; and then I would add just a little bit to it. That was about the result of my estimation in any case.
