1. 111
2. 122
3. 145
4. 133

Answer 1

Correct Answer - Option 1 : 111

The correct answer is 111.

• Each latitude on earth is equal to almost 111 kilometers.
• This distance decreases marginally as one travels to poles and increases marginally as one goes towards the equator.

• Latitude
  • Imaginary lines running east-west.
• Longitude
  • The vertical lines running north-south, join the two poles. 
• The earth is totally taken to be at 360°. Therefore it has 360 meridians. 1 meridian = 1°.
• 1° longitude = 4 Minutes.
• 180° longitude = 180 × 4 = 720 minutes = 12 hrs
• The Prime Meridian (0°) runs through the Greenwich Observatory in England, the location agreed upon by a conference in 1884.
• On the opposite side of the Earth is the international dateline at approximately 180° longitude.
