Where is it colder at 3:00, Jonestown or Cooperville?

Answer 1

The Jonestown will be much colder compare to the Cooperville.
See how the solution goes:
At 1:00, the both share the same temperature
Let X = the temperature of both town

Jonestown
=> 1:00 = x
=> 2:00 = x – 10
=> 3:00 = x – 10 – 8
At 3:00, Jonestown dropped a total of 18 degrees

Cooperville
=> 1:00 = x
=> 2:00 = x – 6
=> 3:00 = x – 6 – 2
At 3:00, Cooperville dropped 8 degrees only.
