Mujhe samajhane ki kripya pradhan kare

Hi guys I am prathamesh ahire

And I am trying to solve this question

Width- 30 km

Flight lines - 16

Therefore total flights - 15

Then width of 1 (one) flight - 30/15 = 2 km

As given scale is 1:50000 ( means 1cm = 50000 cm )

We know that , 1 km = 100000 cm

Therefore , for 2km scale will be 4 cm

How it is.?

16 lines divide the area to 15 spacings, so

Distance / spacing = 30/15.

Equate it with (map/ground)

=>1/50,000= x/ (3/15)

X= 4cm

I want to discuss this question

[30÷(16-1)]×1000×100÷50000=4

30 km = 30 x 1000 x 100 cm

Scale on Map = 1: 50,000

Area on Map = (30 x 1000 x 100)/50000 = 60

IF 16 lines divide the area into 15 parts, then 60/15 = 4

i.e. Distance between two flights is 4 cm

Flight lines = (Width(coverage)/spacing)

16 = (30,000/x)

x = 30,000 / 16

x = 1875

scale = map/ ground

1/50,000 = x / 1875

x = 0.0375 m = 3.75 cm ~~ 4cm

Flight lines = (Width(coverage)/spacing)

16 = (30,000/x)

x = 30,000 / 16

x = 1875

scale = map/ ground

1/50,000 = x / 1875

x = 0.0375 m = 3.75 cm ~~ 4cm

Yes

30,000/16=1875

1875/50,000 m =0.0375 Cm

~~4 cm

reason??# of Flight lines = (Width(coverage)/spacing)

16 = (30,000/x)

x = 30,000 / 16

x = 1875

scale = map/ ground

1/50,000 = x / 1875

x = 0.0375 m = 3.75 cm ~~ 4cm

(30*100000)/(50000*(16-1))=4cm

# of Flight lines = (Width(coverage)/spacing)

16 = (30,000/x)

x = 30,000 / 16

x = 1875

scale = map/ ground

1/50,000 = x / 1875

x = 0.0375 m = 3.75 cm ~~ 4cm
