Problema Solution
At 1:00 PM, the water travel in a pool is 13 inches. At 2:30 PM, the water level is 28 inches. What is the rate of change (inches/hour) if y=10*+0?
Answer provided by our tutors
the change in time is:
2:30 PM - 1:00 PM = 1 h 30 min = 1.5 h
the rate of change v is:
v = (28 - 13)/1.5
v = 10 in/h
the rate of change is 10 inches/hour.
