Answer:

78.5 %

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 fr
timurjin [86]

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
