a.
Tofind:the change in the width of the beachfront from low to high tide.
a.
Answer to Problem 52CCR
Change in the width of the beachfront from low to high tide is 102 feet.
Explanation of Solution
Given information:
Consider the information provided, during the low tide in Wrightsville, North Carolina, the beachfront in some places is about 350 feet from the ocean to the homes. High tide can change the width of the bench at a rate of 17 feet an hour. It takes 6 hour for the ocean to move from low to high tide.
Calculation:
To find thechange in the width of the beachfront from low to high tide, the rate of the change of the width of the beach is to be multiplied by the time taken.
So,
Therefore, change in the width of the beachfront from low to high tide is 102 feet.
b.
To find:the distance from the ocean to the homes at high tide.
b.
Answer to Problem 52CCR
The distance from the ocean to the homes at high tide is 248 feet.
Explanation of Solution
Given information:
Consider the information provided, , during the low tide in Wrightsville, North Carolina, the beachfront in some places is about 350 feet from the ocean to the homes. High tide can change the width of the bench at a rate of 17 feet an hour. It takes 6 hour for the ocean to move from low to high tide.
Calculation:
The distance from the ocean to the homes during high tide is-
Therefore, the distance from the ocean to the homes during high tide is 248 feet.
