In this question
1 km to 10 km scale is used
Lcos 60 (cos 60 = 1/2)
1000×1/2
500km
Lcos@ = 100cos60° = 100x(1/2) = 50
Formula is Lcos∅
Here L - 100 , ∅= 60°
So, Lcos∅ = 100cos60° = 100x(1/2) = 50
1000 km in the place of 100km, then it would be 500km.
Latitude = Lcosθ = 1000x 1/2=500.
1000 km in the place of 100km, then it would be 500km.
Latitude = Lcosθ = 1000x 1/2=500.
