Andy is scuba diving. he starts at sea level and then descends 10 feet in 212 minutes. part a how would you represent andy's descent as a unit rate? express your answer as an integer. enter your answer in the box

I would use the starting position, sea level as zero. Then I would convert all those minutes to hours so the answer is an integer and not a decimal.
60 min * (-10 ft / 212 min) = -2.83 ft/hr

round to integer = -3 ft/hr
