DISTANCE

inwards/outwards:

radius r62 - r52 = 10 x 100m = 1.000m

--------

Time-space / Minutes distance

A)

From m10:2 to m10 = 200m counter clockwise

B)

from m10 to m9:17 :

The with of a sector (minutus maximus) is radius/2!

(Confirm: 360 / 12 = 30 degrees, sin 30 = 0,5)

On average radius r58, minutus maximus = :58/2 - :29 width sector

Distance to m9:17 = :29 - :17 = :12 = 1.200m

A) + B): 1200 + 200 = 1400m  counter clockwise
