Question

When it is 6:00 a.m. in Honolulu, it is 3:00 p.m. in London. Just before Paul’s flight from Honolulu to London, he called his friend Nigel, who lives in London, asking what kind of clothing to bring. Nigel explained that London was in the middle of some truly peculiar weather. The temperature was currently 30°C, and was dropping steadily at a rate of 1°C per hour. Paul’s flight left Honolulu at 2:00 p.m. Thursday, Honolulu time, and got into London at 12:00 p.m. Friday, London time. What kind of clothing would have been appropriate for Paul to be wearing when he got off the plane? a. shorts and sandals, appropriate for around 90-105°F b. winter wear, appropriate for around 20-45°F c. street clothes, appropriate for around 70-85°F d. a light jacket, appropriate for around 50-65°F

Answer 1

b. winter wear, appropriate for around 20-45°F c.

Explanation:

Answer 2

b. winter wear, appropriate for around 20-45°F

Explanation:

When it is 6:00 hours in Honolulu, it is 15:00 hours in London, this means that there are 15 - 6 = 9 hours of difference.

Paul got into London at 12:00 p.m, that is, at 12 - 9 = 3:00 p.m. Friday Honolulu time. Paul’s flight left Honolulu at 2:00 p.m. Thursday, so he spent 25 hours flighting.

When the flight started, the temperature in London was 30 °C, after 25 hours the temperature dropped 25 °C, so it was 30 - 25 = 5 °C.

To convert from °C to °F, we use the following formula:

(x °C × 9/5) + 32 = y °F

Replacing with x = 5

(5 °C × 9/5) + 32 = 41 °F
