Question

The ocean's level changes throughout the day, rising and falling in a regular cycle known as tides. A tide table indicates the times when the water reaches high tide and when it drops to low tide at a specific place. Examine the tide table below to observe these patterns.
day 4 high tide 5:20 am
day 5 high tide 6:55am
day 6 high tide 8:16am


What would you predict would be a possible time for a high tide on Day 7?

Answer 1

To predict the time of high tide on Day 7, we can observe the pattern in the tide table provided.

- Day 4: High tide at 5:20 AM
- Day 5: High tide at 6:55 AM (a difference of 1 hour and 35 minutes later than Day 4)
- Day 6: High tide at 8:16 AM (a difference of 1 hour and 21 minutes later than Day 5)

Now, we can see the increments in time between the high tides seem to be decreasing:
- From Day 4 to Day 5: 1 hour and 35 minutes
- From Day 5 to Day 6: 1 hour and 21 minutes

The average increment seems to be decreasing. Based on approximations, we could estimate that the high tide on Day 7 could be around 9:30 AM, following the established pattern and considering a similar interval as the previous days.

Thus, a reasonable prediction for high tide on Day 7 would be **around 9:30 AM**.
