Ascuba diver was exploring a reef 32.12 m below sea level. the diver ascended to the surface at a rate of 8.8 m/min
(a) write an equation to model the situation. use the formula d=rt.
(b) explain why it is reasonable to write the distance, d as a positive number
(c) how long did it take the diver to reach the surface

Thank you for posting your question here at . Below ist he answers:

a. T= d/r
b.  It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something. 
c. T= d/r
T= 32.12 m /8.8 m/min
T= 3.65 min
