Question

choose 2 true statements
A) using Naismith's rule to plan a walk would give different times to walk up a hill as down it, on the same path.

B) On a map with a scale of 1:200 000, 5cm on the map will represent 1km on the ground

C) On a map with a scale os 1:20 000, an area of 4km2 on the ground will be represented by an area of 100cm2 on the map

D) If the bearing of a boat from a lighthouse is 030 degrees then the bearing of the lighthouse from the boat is 150degrees

E) A road gradient of 25% is exactly the same as a mathematical gradient of 0.25

F) The walking distance between 2 hill tops is likely to be the same as the distance between the 2 hill tops calculated using their grid references

Can anyone please help me. I think A is false

E is nonsense.
A is nonsense.
F is nonsense.

So work out B, C, D to see which is false. Careful on C, it is tricky.

I think its' C & D because i get 10km for B not 1km. Is this correct?
