For distance upto 18.2 km is 10 cm.
For distance upto 54.3 km is 30 cm.
For distance upto 91 km is 50 cm.

I can not understand what is right and what is wrong

RAJ KUMAR said:   8 years ago
IN BC PUNMEA 12KM =1 CM.
BUT IT IS WRONG.

IN ACTUAL 18.5 KM=1CM=10MM.

This is the correct one.

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

10 mm is correct.

Angel said:   8 years ago
I think, 10mm is correct.

Avinash Gund said:   8 years ago
For 18.2 km 10 mm is correct.
For 18.5km 15 mm is correct.

Naveen said:   8 years ago
The correct answer must 15mm.

ARVIND said:   8 years ago
IT SHOULD BE 15mm.

For 12km=10mm (as per BC PUNMIA).
So,for 18.2 km = 15mm.

10mm = 1 cm is the correct answer.
