A scuba 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) Why do we write the distance, d, as a positive number?
(c) How long did it take the diver to reach the surface?
Answer:

a) Write an equation to model the situation using the formula, d = rt; d = distance, r = rate, and t = time. (2 pts)




b) Why do we write the distance, d, as a positive number? (1 pt)




c) How long did it take the diver to reach the surface? (2 pts)
