Step 1 of 2: The bottom of the Kermadec Trench is about 1500 feet deeper than 21 times the maximum depth of Adams Lake. Find an equation to express the depth of the Kermadec Trench, k, in terms of the depth of Adams Lake, a. Then solve your equation for a to find
the depth of Adams Lake in terms of the depth of the Kermadec Trench
