Question

The temperature outside is 50 degrees. If the temperature increases 3 degrees every hour, for how many hours will the temperature be less than 71 degrees?

Answer 1

6 more hours

Explanation:

71 - 50 = 21

21/3 = 7

-------------------------------------------------

Subtract since 71 is the max

Then, since the answer cannot be equal to 71 but less than 71, the answer is 6.
