Question

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 12:00 p.m. Thursday, Honolulu time, and got into London at 1:00 p.m. Friday, London time. What kind of clothing would have been appropriate for Paul to be wearing when he got off the plane? (Use the formula F = (9/5)C + 32)
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

Honolulu is 10 hours behind London, so 12:00 p.m. Thursday HST is 10:00 p.m. Thursday in London. Arrival at 1:00 p.m. Friday London time means the plane was in the air 15 hours.

Temperature after 15 hours: C = 30 − 15 = 15°C.
Convert to Fahrenheit: F = (9/5)·15 + 32 = 27 + 32 = 59°F.

59°F fits the "a light jacket, appropriate for around 50–65°F" category.

Answer: d.
