a.
To approximate:
The age of Suiko to the nearest tenth of a million years, if Suiko is 4794 kilometers from Kilauea.
a.
Answer to Problem 40E
The age of Suiko would be approximately 59.6 million years.
Explanation of Solution
Given:
The Hawaiian-Emperor chain of volcanoes is shown below.
The age a (in millions of years) of a volcano in the chain can be approximated by
Calculation:
To find Suiko’s age, we will substitute
Therefore, the age of Suiko would be approximately 59.6 million years.
b.
To approximate:
Midway’s distance along the chain from Kilaueato the nearest ten kilometers, if Midawayis about 27.7 million years old.
b.
Answer to Problem 40E
Midway’s distance along the chain from Kilauea would be approximately 2320kilometers.
Explanation of Solution
Given:
The Hawaiian-Emperor chain of volcanoes is shown below.
The age a (inmillions of years) of a volcano in the chain can be approximated by
Calculation:
