Nikki is fishing from a bank 27 feet above water level. In this location, the fish tend to feed at
37 feet below the surface. How long must Nikki's fish line be to reach the fish?
Nikki is 27 feet above the water, and the fish are 37 feet below. So the line needs to stretch that distance.
27 - (-37) = 64 feetposted by Marth
