Question

Andy is scuba diving. He starts at sea level and then descends 10 feet in 212 minutes.

Answer 1

Descent = 10 feet

Time required = 2 1/2 minutes.

The rate of descent = (10 feet)/(2.5 mn) = 4 ft/min

In 6 minutes, the descent will be

(4 ft/min)*(6 min) = 24 ft

Answer:

(a) 4 feet/minute

(b) 24 feet
