Andy is scuba diving. He starts at sea level and then descends 10 feet in 212 minutes. How would you represent Andy’s descent as a unit rate? Express your answer as an integer. If he continues at this rate, where will Andy be in relation to sea level after 6 minutes?

Answer 1

-10ft/212min = -0.047 ft/min
in another 6 minutes, he will dive another x feet, with x such that
x/6 = 10/212

wow -- it takes him 3 1/2 hours to go down 10 feet? That's almighty slow!
