Answer: 28 feet.
Step-by-step explanation:
Given: During the winter months, freshwater fish sense the water getting colder and swim to the bottom of lakes and rivers to find warmer water.
The total depth of the lake = 32 feet
Since, fish swims 7/8 of the depth, then the depth of lake to which the fish swim=[tex]\frac{7}{8}\times32\ feet[/tex]
Since, [tex]32\div8=4[/tex]
therefore, [tex]\frac{7}{8}\times32=7\times4=28[/tex]
Hence, the fish swim 28 feet in lake.
