A diver begins at 140 feet below sea level. She descends at a steady rate of 7 feet per minute for 4.5 minutes. Then, she ascends 112.2 feet. What is her current depth? mc010-1.jpg feet mc010-2.jpg feet 59.3 feet 549.3 feet
Answer: So 7*4.5=31.5 ft next what you have to do is add 31.5 ft to 140 ft which is 171.5 ft next you need to subtract 112.2 ft from 171.5 ft which means that the divers current depth must be 59.3 Ft.
