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? Negative 549. 3 feet Negative 59. 3 feet 59. 3 feet 549. 3 feet.

Answer 1

-59.3 ft

4.5 x 7 = 31.5

140 + 31.5 = 171.5

171.5 - 112.2 = 59.3

she is below sea level so it is negative.
