Explanation:
Given
below sea level
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
Required
Determine the elevation of the Sea of Galilee
We have that the lowest elevation in Lammefjord is:
![Lowest\ Elevation = -23ft](https://img.qammunity.org/2021/formulas/mathematics/high-school/16oyh0rnv1zh3rxmqegsae04f9azwpa9bt.png)
It is negative because, the elevation is below sea level.
Calculating the elevation of Sea of Galilee, we have:
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
![Sea\ of\ Galilee = 30 * -23ft](https://img.qammunity.org/2021/formulas/mathematics/high-school/akoej0hlgoyrcbffdqyvi098vfhidckrqz.png)
![Sea\ of\ Galilee = -690ft](https://img.qammunity.org/2021/formulas/mathematics/high-school/pbop67pkwetpzamzchymjhcrskxpm94x7b.png)
Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level
