●Step-1

Calculation for statement scale:

According to the question, R.F. = Map distance (NUMERATOR); Ground distance

(Dinominator)

Now,

ASSUMING the Numerator in INCH, so both are considered as "Inch" unit an according to R.F. 1 inch is Numerator and 60,000 miles is Dinominator and 60,000 inch has to be

converted into "mile".

1 inch in the map distance REPRESENTED by =60,000 inch on the real ground.

1 inch in the map distance represented by =60,000/63360 (1mile = 63360 inch

= 0.95 mile

So,

The statement scale 1 inch t

0.95 mile.

●Step-2

Calculations for total length of the scale:

SUPPOSE, we take 5 mile total scale, so the

length of the scale will be,

0.95 mile on the ground distance represented

by= 1 inch in the map.

1 mile on the ground distance represented

by=1/0.95 in the map.

5 mile on the ground distance

represented by= 5x100/0.95 in the map.

= 5.3 inch

●Step-3

Numbers of primary division:

VALUE of total length of the scale / Value of one primary division

= 5 mile/ 1 mile

= 5

●Step-4

Numbers of secondary division:

Value of one primary division/Value of Secondary division

= 1 mile / 1/2 mile

= 2
