A scuba diver descends farther down into the ocean from an initial depth of 14.7 feet below sea level. The scuba diver descends
uranmaximum [27]

The maximum rate, r, that the scuba diver may descend is r≤ 11.2

Given the following parameters:

  • Initial length = 14.7feet
  • Time = 4.5 minutes
  • Rate  = distance/time

If the scuba diver reaches a depth no more than 65.1 feet below sea level, then;

r ≤ (65.1 - 14.7)/4.5

r≤ 50.4/4.5

r≤ 11.2

Hence the maximum rate, r, that the scuba diver may descend is r≤ 11.2
