Answer 1

Daytime in different cities

Explanation:

• Though the sun rises and sets at different times in different places, all of them have the same daytime.
• Day and night is caused by rotation of earth. The Earth rotates from West to East, therefore, the Sun appears to rise from East and appears to set in the West even though the Sun is actually stationary at the center of the Solar system.
• When the light from the sun falls on the Earth, the part of Earth facing the sun experiences day, and the part of Earth facing away from the sun experiences night.
• As the earth rotates, days and nights alternate. Ideal time period for day and night for ideal spherical globe is 12 hours each.
• To calculate time of day and easily and precisely for every place on earth, Earth is imagined to have imaginary lines called longitudes running from north pole to south pole.
• These help to know the angle in degrees by which the earth has rotated while the sunlight has reached from one longitude to the other and vice versa is used to tell the time of the day.
• Greenwich Standard meridian represents 0°.
• Longitudes to the west of of it are denoted in degrees followed by W. and longitudes to east of it are denoted in degrees followed by E. (Your east and west when you look at it on the globe.)
• So by observing the values in the question you can say that since the sun sets early in Madurai at 5:42 pm, it is at the east of Hyderabad where sun sets at 6:49 pm and so on for the other places. (Your east as you look on the points on the globe)
