Question

At noon the temperature was -10° F. Over the next 4 hours the temperature went up 12°. Then every hour until 10 pm the temperature dropped 2°. What was the temperature at 10 pm?

Answer 1

Answer: 0º F.

Explanation:

Noon = 12 pm

At Noon it was -10º F, over the next 4 hours it went up to 12º F.

Noon + 4 hours = 4 pm

The temperature dropped 2º F every hour until 10 pm which means for 6 hours the temperature dropped.

6x2º F = 12º F which means the temperature dropped by 12º F.

12º F - 12º F = 0º F

Answer 2

-10 degrees

Explanation:

at noon the temp was -10. -10 + 12 = 2 and that is at 4 o'clock 2- 6 hours ( time until 10 pm) x 2. 2 - 12 = -10.
