16 lines means 15 strips ( two strips having 3 lines).

Thus, No. Of strips = 15.
Total area/ total strips = area of one strip.
30 km/ 15 = 2.
scale 1cm= 0.5 km.
Hence the spacing will be 2/0.5 = 4.

Flight line 16 means no. of strips required to cover length 30km is 16 + 1 = 17.
Now, 30km/17= 1.76 say 2km.

Flight line 16 means no. of strips required to cover length 30km is 16+1=17.
Now, 30km/17= 1.76 say 2km.
Scale 1 cm = 0.5 km.
2/0.5 = 4 cm.

Scale is 1cm= 0.5km.
Now 30km/16=1.82 say 2km.
Therefore
Ans is 4cm.
