If you add up the total number of low tide bottoms and high tide peaks over a period of 25 hours, then what is the total number that you can see if you started counting right after the passage of the high tide peak (do not count this starting peak)?
Question
If you add up the total number of low tide bottoms and high tide peaks over a period of 25 hours, then what is the total number that you can see if you started counting right after the passage of the high tide peak (do not count this starting peak)?
Solution
Tides typically occur twice a day, which means there are usually two high tides and two low tides each day. This is due to the gravitational pull of the moon and the rotation of the earth.
-
In a 24-hour period, you would typically see 2 high tide peaks and 2 low tide bottoms.
-
However, the question specifies a 25-hour period. Tides are not perfectly aligned with our 24-hour day; they actually occur approximately every 12.42 hours. This means that over a 25-hour period, you would see an additional high tide peak and low tide bottom.
-
So, in a 25-hour period, you would typically see 3 high tide peaks and 3 low tide bottoms.
-
However, the question specifies that you start counting right after the passage of a high tide peak, and not to count this starting peak. This means you would subtract one from the total.
-
Therefore, over a 25-hour period starting right after the passage of a high tide peak, you would see a total of 5 tides (2 high tide peaks and 3 low tide bottoms).

When the tide rises, the water level will also rise, causing the ladder to rise with it. Since the ladder is 200cm long and the distance between each rung is 20cm, there are a total of 10 rungs on the ladder.Initially, the bottom rung touches the water, so the water level is at 0cm. As the tide rises at a rate of 10cm per hour, the water level will reach the first rung after 1 hour, the second rung after 2 hours, and so on.To find out when the water will reach the fifth rung, we need to calculate how many hours it will take for the water level to rise to 80cm (4 rungs x 20cm each).Since the tide rises at a rate of 10cm per hour, it will take 8 hours (80cm / 10cm per hour) for the water to reach the fifth rung.
