Question

On a certain day, the temperature changed at a rate of 3°F per hour. How long did it take for the change in temperature to be -33°F?

​

Answer 1

I think 11 hours.

Explanation:

If I know starting temp such as 0 degrees then I can say that it would take 11 hours as 11*3 = 33. If it is 3 degrees, then it would 3*12 = 36 degrees.
