Alright Blomme — let's do this. 1.1.1 The country in the Southern Hemisphere that has three time zones is Australia. 1.1.2 Two facts about the 0° (zero degree) line of longitude (Prime Meridian) that would interest a tourist: • Tourists can visit the Royal Observatory in Greenwich, London, and stand with one foot in the Eastern Hemisphere and one in the Western Hemisphere. • The Prime Meridian passes through several countries in Europe and Africa, offering a unique opportunity to travel across the line that defines global time zones in places like Ghana or France. 1.2.1 a) Step 1: Identify the time zones for Johannesburg and Rome. Johannesburg (South Africa Standard Time, SAST) is UTC+2. Rome (Central European Time, CET) in February is UTC+1. Step 2: Calculate the time difference. $$ \text{Time difference} = (\text{UTC+2}) - (\text{UTC+1}) = 1 \text{ hour} $$ Johannesburg is 1 hour ahead of Rome. The time difference between Johannesburg and Rome is 1 hour. b) Step 1: Calculate the arrival time in Johannesburg's time zone. Departure time: 14:00 on 6 February 2018 (Johannesburg time) Flight duration: 14 hours $$ \text{Arrival time (JHB)} = 14:00 + 14 \text{ hours} = 28:00 \text{ on 6 Feb} $$ $$ 28:00 \text{ on 6 Feb} = 04:00 \text{ on 7 Feb} $$ Step 2: Adjust for the time difference to Rome. Rome is 1 hour behind Johannesburg. $$ \text{Arrival time (Rome)} = 04:00 \text{ on 7 Feb} - 1 \text{ hour} = 03:00 \text{ on 7 Feb} $$ Karlien will arrive in Rome at 03:00 on 7 February 2018. c) Step 1: Identify the time zones for Rome and New York. Rome (CET) is UTC+1. New York (Eastern Standard Time, EST) in February is UTC-5. Step 2: Calculate the time difference between Rome and New York. $$ \text{Time difference} = (\text{UTC+1}) - (\text{UTC-5}) = 1 - (-5) = 6 \text{ hours} $$ Rome is 6 hours ahead of New York. Step 3: Calculate the time in New York. Current time in Rome: 08:00 $$ \text{Time in New York} = 08:00 - 6 \text{ hours} = 02:00 $$ Her friend will receive the phone call in New York at 02:00. 1.2.2 a) Daylight Saving Time (DST) is the practice of advancing clocks by one hour during warmer months, typically in spring, so that evening daylight lasts longer. Clocks are then set back by one hour in autumn. b) Two positive impacts of daylight saving time for London: • Energy Conservation: By shifting daylight to the evening, the need for artificial lighting in homes and businesses is reduced, leading to energy savings. • Economic Benefits: Extended daylight in the evenings encourages more outdoor activities, shopping, and dining, which can boost local tourism and retail industries.
