Answer 1

Answer: r≤10.4

Step-by-step explanation:

Initial depth - 12.8 feet

Maximum depth reached - 49.2 feet

49.2-12.8= 36.4 feet (maximum descent that the scuba diver can make)

Rate = Distance ÷ time

Distance - 36.4 feet

Time - 3.5 minutes

r= $\frac{36.4}{3.5}$

r= 10.4

As r is the maxmimum rate found, r cannot be greater than 10.4, so r must be less than or equal to 10.4.

Therefore, r≤10.4
