To answer this you will need to write the ratio of difference in the tides over the amount of time that goes by.
1. 3.21 ft - 0.20 ft= 3.01 ft change.
2. 3.01 change over 6 5/12 hr.
3. Divide these to find the lapse rate per hour. This is about 0.47 ft per hour.
The answer is 1 1/4 because 1/2 is equal to 2/4 and 2/4 + 3/4 = 5/4. 5/4 is equal to 1 1/4. Hope this helps!
