You're on a roll — here are the answers to the questions: 4. Choose the correct answers— a)* A traveller will have the feeling of loss/gain in his time, if he moves to the west of Greenwich as per the GMT. The correct answer is gain. When moving west from Greenwich, you move to earlier time zones, so you gain time (the clock goes back). b)* Mumbai has early sunrise than Greenwich therefore Mumbai is located at the east/west longitude. The correct answer is east. Places to the east of the Prime Meridian experience sunrise earlier. c)* Time in each longitude to the east of the Prime Meridian goes ahead/back by four minutes. The correct answer is ahead. For every 1^ of longitude to the east, time moves ahead by 4 minutes. d)* The east longitude of 83^ 20'/90^/82^ 30' is accepted as the Indian Standard longitude. The correct answer is 82^ 30'. This is the standard meridian for Indian Standard Time (IST). e)* The common watch that we wear runs according to the local time/Greenwich Mean Time/Indian Standard Time. The correct answer is local time. Our watches typically show the local time of our current location. 5. Write down the differences between— a)* Latitudes and Longitudes: Latitudes* are imaginary horizontal lines that run parallel to the Equator, measuring distance north or south. They range from 0^ to 90^ N/S. Longitudes* are imaginary vertical lines (meridians) that run from the North Pole to the South Pole, measuring distance east or west of the Prime Meridian. They range from 0^ to 180^ E/W. b)* Local Time and Standard Time: Local Time* is the time of a specific place determined by the apparent position of the sun at that meridian. It varies from place to place. Standard Time* is the uniform time adopted for a country or a region, based on the central meridian of that area. It helps avoid confusion caused by varying local times. 6. Solve the following problem— a)* When it is 7 hrs in Greenwich (as per the GMT), then in a particular place, it is 12 noon. Find out the longitude of that place. Step 1: Calculate the time difference. Time difference = 12:00 noon - 7:00 hrs = 5 hours Step 2: Convert the time difference to minutes. 5 hours × 60 minutes/hour = 300 minutes Step 3: Calculate the longitude difference. Since 1^ of longitude corresponds to 4 minutes, divide the total minutes by 4. Longitude difference = 300 minutes4 minutes/degree = 75^ Step 4: Determine the direction. Since the local time (12 noon) is ahead of GMT (7 hrs), the place is to the east of Greenwich. Longitude = 75^ E b)* A wireless message was sent from New York (75^W) city to Los Angeles (180^W) at about 12 noon. At what time was the message sent as per the local time of Los Angeles? Correction*: Los Angeles is approximately 118^W, not 180^W. Assuming the question intends to use 180^W for calculation purposes, or if 180^W is a typo for a different city, I will proceed with the given values. However, 180^W is the International Date Line, which is not a city. Let's assume the question meant a location at 180^W. Step 1: Find the longitude difference between New York (75^W) and the location at 180^W. Longitude difference = 180^ W - 75^ W = 105^ Step 2: Calculate the time difference. Since 1^ of longitude corresponds to 4 minutes. Time difference = 105^ × 4 minutes/degree = 420 minutes Step 3: Convert minutes to hours. 420 minutes = (420)/(60) hours = 7 hours Step 4: Determine the time in Los Angeles (or the location at 180^W). Since Los Angeles is to the west of New York, its time will be behind New York's time. Time in Los Angeles = 12:00 noon - 7 hours = 5:00 A.M. The message was sent at 5:00 A.M. local time in Los Angeles (or the location at 180^W). c)* What will be the exact time of a game to be held in Dhubri (90^E) as per its local time, when the same can be held in New Delhi (77^E) at 9 A.M. Step 1: Find the longitude difference between New Delhi (77^E) and Dhubri (90^E). Longitude difference = 90^ E - 77^ E = 13^ Step 2: Calculate the time difference. Time difference = 13^ × 4 minutes/degree = 52 minutes Step 3: Determine the time in Dhubri. Since Dhubri is to the east of New Delhi, its time will be ahead of New Delhi's time. Time in Dhubri = 9:00 A.M. + 52 minutes = 9:52 A.M. The game will be held at 9:52 A.M. local time in Dhubri. That's all for this set! What's next?
