Been a long time since schooldays, 60 odd years to be frank.
Anyway, I have a problem with trying to figure out how large an object of 1cm would appear to someone who is 9.2 metres away from it.
This relates to the size of text on a car park sign where the text is only a centimetre high and driver is passing by at a distance of 9.2 metres.
I have a belief that the text would be so small as to make it unreadable. I really do need an answer on this though so if anyone can assist I'd appreciate it, however if a formula of sorts can be given I may be able to work it out myself.
Many thanks
