After diving 86 feet below the surface, a diver ascends at 4 feet per minute. After 12 minutes pass, where is the diver located in relation to the surface? Please include how you solve the question, it'll be very appreciated thnx guys ^ ^
One possible way: -86+(4*12)=-38 -86 is the number where the diver is. 86 feet below the surface. 4*12 is the total number of feet he has ascended in 12 minutes. Because he is ascending, so you add 4*12 (or 48) to -86. The answer is -38, meaning he's 38 feet below the surface.
