Final answer:
By working backwards from the temperature at 3 pm (-2 degrees) to determine the temperature at 1 pm (5 degrees), and then comparing the increases from the morning hours, we deduce the temperatures at 7 am and 11 am. The correct temperatures are 7 am: 0 degrees, 11 am: -2 degrees, and 1 pm: 3 degrees, making answer B correct.
Step-by-step explanation:
Let's solve the problem step by step to fill in the missing temperature values for 7 am, 11 am, and 1 pm. Since the temperature increase from 7 am to 9 am is the same as from 11 am to 1 pm, and it decreased by 7 degrees from 1 pm to 3 pm when it was -2 degrees, we can work backwards to find the temperatures at 1 pm and 11 am. First, if the temperature at 3 pm is -2 degrees and it has decreased by 7 degrees since 1 pm, the temperature at 1 pm must have been -2 + 7 = 5 degrees. Knowing that the change from 9 am to 11 am is the same as from 7 am to 9 am, we can see that there was a 5 degree increase from 9 am (4 degrees) to 1 pm (5 degrees), meaning the temperature at 11 am had to be 4 degrees as well. Now, to find the temperature at 7 am, we subtract the 5 degree increase from 9 am's temperature of 4 degrees, giving us 4 - 5 = -1 degrees.
Thus, the temperatures are:
- 7 am: -1 degree
- 11 am: 4 degrees
- 1 pm: 5 degrees
Therefore, the correct answer is B. 0, -2, 3.
