30 cm in a length of 54.5 km.
50 cm in a length of 91 km.

For 18.2km - 0.1m=10cm,
For 54.3km- 0.3m=30cm,
For 91km- 0.5m=50cm.

@Raihan.

Number of the difference between the arc length and its subtended chord on the earth surface for a distance of 18.2 km is 0.1 m. So the correct option is (c) 10 cm.

0.1 m so 10 cm.

But in a book of surveying, the difference is 1cm for 12 km distance so how it is possible to 10 cm for 18.2 km? As per book answer will be 1.5 cm.

I think units are in mm not cm.

It's 10mm not 10cm.

Ashu said:   8 years ago
10mm = 1 cm is the correct answer.
