The level of the tide in a harbor changes from 9 1/4 to 4 1/2 above sea level over a period of 3 1/4 h. Whatbis the rate of change in the tide level over this period of time?

The answer should be -19/13 per hour. I think, I'm not completely sure.

Step-by-step explanation:

Find the difference of 9 1/4 and 4 1/2

divide by 3 1/4

simplify

4 1/2 - 9 1/4 = -19/4

-19/4 divided by 13/4 = -76/52

-76/52 = -38/26 = -19/13

So the answer should be -19/13 per hour.
