from Kirkby station

m1:1 r103

to Melling primary school

m12:48 r104

- m1 to m12

and

- r103 to r104

= counter clockwise

and

= almost same radius

distance

inwards/outwards: radius r104 - r103 = 100m

--------

Time-space / Minutes distance

A) from m1 to m1:1 = 100m

B) from m1 to m12:48

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

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

On radius r104, minutes distance = :104/2 = :52

(Remark: m12:52 r104 is the same as m1 r104)

Distance =  :52 - :48 = 400 m

A) + B) 400 + 100 = 500m

flight distance / Hipotenuse:

- more than 100 m

- less than 500 + 100 m
