From Clan William NDB CW to Kimberley VOR KMV, distance 364 nm. At 116 nm from CW the A/c is 11 nm right of planned. To fly direct KMV from this
position, heading must be changed:
(a) 6 degrees left
(b) 8 degrees left
(c) 12 degrees left

On a Mercator chart:
(a) Distance is measured along a straight line because that is the shortest distance between two points.
(b) The shortest earth distance between two points can be represented by a curved line. (G/C = curved line.)
