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 elevation is below sea level. Account for this in your answer.)

Question

__ ft

Answer 1

Lake Profondo: 84 feet deep
Lake Segundo: 5/6 of Lake Profondo's depth

Lake Segundo depth: (5/6) * 84 = 70 feet

Since the elevation is below sea level, we would say that the elevation at the bottom of Lake Segundo is -70 feet.
