Question

When it is 4:00 a.m. in Honolulu, it is 2:00 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 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

D

Honolulu → London is +10 hours, so Paul’s flight left at 10:00 p.m. Thursday London time and arrived 1:00 p.m. Friday — a 15-hour interval. Temperature falls 1°C/hour: 30°C − 15°C = 15°C. Convert: F = (9/5)*15 + 32 = 59°F, so a light jacket (50–65°F) is appropriate.
