Hi,
Having trouble with this one,
'On a mercator chart the distance between two meridians 1deg apart is 7.45cm. What is the scale at 48degN?'
Now, I came out with the answer 1:491,543 = 1:500,000
However the answer given is 1:1000,000?
I worked it out by: 1deg = 60nm so 60nm =7.45cm
60nm = 11112000cm so, divide that by 7.45 and you get 1:1491543.
I just cant see how it could be 1:1000,000?
If anyone could shed some light that would be great.
Thanks
Foz
