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?

Answer 1

Answer:

Paul should be wearing a light jacket appropriate for about 59 F or 15 °C

Step-by-step explanation:

If it is 4:00 a.m. in Honolulu when it is 2:00 p.m. in London, then the difference between times is:

$d=14-4\\d=10\ hours$

London is 10 hours ahead of Honolulu.

If Paul left Honolulu at 12:00 p.m, the corresponding time in London was:

$t=12+10\\t=22 = 10:00\ p.m.$

Since he arrived in London at 1:00 p.m. at Friday, the flight time was:

$F= (24-22)+13\\F=15\ hours$

The flight took 15 hours in total. If the temperature was 30°C when he boarded the flight and it decreases at a rate of 1°C per hour, the temperature when Paul arrives in London is:

$T=30-(15*1)\\T=15^oC$

Converting it to Fahrenheit

$T=(15*\frac{9}{5})+32 \\T=59\ F$

Paul should be wearing a light jacket appropriate for about 59 F or 15 °C
