A cold wave hit Chicago when the temperature hits 62°F during the cold wave the temperature dropped 2° every hour how many hours was it before the temperature was below 40°F

If you are looking for an inequality, the answer is 62-2x<40

For this problem, an important thing to note is how the question says that 'the temperature dropped', meaning that it went down.

This means that the 2 degrees is actually negative.

Then you multiply the change in degrees by hours past:

(-2) * 6=-12

Final Answer:

- 12∘ F
