a. how would you represent Andy's descend as a unit rate? Express your answer as an integer.
b. How much feet can he descend in 6 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:
