Lake Profondo has a depth of 84 feet. Lake Segundo is 5/6 as deep. What is the elevation at the bottom of Lake Segundo? Remember the evaluation is below sea level. Account for this in your answer

Answer 1

Lake Segundo is 5/6 as deep as Lake Profondo, so its depth is (5/6) * 84 feet = <<(5/6)*84=70>>70 feet.
If we account for the fact that the elevation is below sea level, the elevation at the bottom of Lake Segundo would be -70 feet.
