$\frac{1}{2}$
mile or
$\frac{1}{2}$
km on secondary division represented by, where R.F. is 1:60,000.​

●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

Answer 2

Answer:

Condensation can also produce water droplets on the outside of soda cans or glasses of cold water. When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. When a pocket of air becomes full of water vapor, clouds form.
