Question

The graph below shows ocean tide height in feet (ft) over a 44-hour period for a coastal location in the

northeastern United States. The dots represent either high or low tides.
If the pattern shown continued, the next low tide occurred on Day 3 at approximately
(1) 12 midnight
(2) 1:30 a.m.
(3) 1:00 p.m.
(4) 6:00 p.m.

Answer 1

If you clearly see the diagram, you can see that every tide, either low or high, has a difference of 6 to 7 hours for each peak. So if the pattern continues and the last peak was at 7 or 7:30 pm as shown in the table on day 2, then you can do the calculations and see that the most acuurate option is number 2: 1:30 am.
