Answer:

-14.25 degrees Fahrenheit was the temperature after 10 hours.

Step-by-step explanation:

The temperature before sunrise = -11°F

Temperature after rise by 1/2 degree  each hour for 7 hours that id before dropping.

T=(-11 + \frac{1}{2}\times 7)^oF=-7.5^oF

Now after 7 hours drop in temperature takes place 2\frac{1}{4} degrees each hour for 3 hours, sat T'

T'=(-7.5-2\frac{1}{4}\times 3)^oF

T'=(-7.5-\frac{9}{4}\times 3)^oF=-14.25^oF

-14.25 degrees Fahrenheit was the temperature after 10 hours.
