At 10: 07 p. m. you find a secret agent murdered. next to her is a martini that got shaken before the secret agent could stir it. the room temperature is 70◦f. the martini warms from 60◦f to 61◦f in the 2 minutes from 10: 07 p. m. to 10: 09 p. m. if the secret agent’s martinis are always served at 40◦f, what was her time of death, to the nearest minute?

Her time of death was 9:27 P.M.

Explanation:

Since the martini warmed from 60°F to 61°F in 2 minutes,

Therefore, it takes 2 minutes for the temperature to rise by 1°F.

At 10:07 P.M. (when the secret agent was found dead), the temperature of the martini was 60°F.

Martini's are served at 40°F.

Temperature change of the martini from when it was served to when the agent was murdered = 60 - 40 =20°F

If 1°F = 2 minutes,

then 20°F = 40 minutes.

40 minutes before 10:07 P.M is 9:27 P.M.

Therefore the agent was murdered around 9.27 P.M.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.

are there any options?
