Geography paper 2 for friday

<< < (3/3)

sipoon77:
About the Scale, they usually give you either  1:50,000  or 1:25,000
My teacher said something about converting it to metres but i forgot :-\
Or do you just use that other scale at the bottom? I don't know how to use it  :o

They say 2 cm is 1 km (one grid square)...
Then we gotta change to metres?? I'm confused lol

2cm:1km=1000m=100000cm
2cm:100000cm
1:50000
you cpuld divide any map measurement in cm by 2 to get the real distance in km or times the real measurement in km by 2 to get the map measurement in cm

hey can anybody please send me the map extracts for the years 2008 and 2007 to my email acheweiky123@hotmail.com?
and goodluck everyone

I'm kind of freaking out right now about finding the gradient on a map because my teacher told me that when you measure the straight line distance on a map, it gives you the hypotenuse of the triangle. Therefore, to find out the gradient, you would have to use Pythagorus' theorum to find the horizontal distance. Personally, I think that sounds completely wrong, because OS maps don't take contours into account when mapping distance. Can anybody help me - does the straight line distance = the horizontal distance between two points, or is it equal to the hypotenuse?
I don't know if any of that made sense...

your teacher sounds retarded :p
to find the horizontal distance between two points just use the scale given below the map (0-1 km) km is less than a mile and equal to 1000 meters.Just mark it on ur ruler or a piece of paper and measure the distance your self.
oh and remember give the answer in meters.
