Question

A dolphin swimming 24 feet below the ocean's surface dives 18 feet straight down. How many feet below the ocean's surface is the dolphin

Answer 1

the ocean is at 0. So 24 ft below the surface is -24...and he dives down another 18 ft.......-24 - 18 = - 42.

so now he is at -42 or 42 ft below the surface

Answer 2

24 feet is the starting point, must account for it since its below the oceans surface, straight down 18 is just 18 more feet down. 42 feet below the oceans surface
