Problema Solution
a scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 100 feet below the surface after 40 seconds. What is the scuba divers rate of change
Answer provided by our tutors
An average rate of change is a rate that describes how one quantity changes (in our case the distance) in relation to another quantity (in our case the time):
(100 - 10)/(40 - 10) = 90/30 = 3 ft per second
The rate of change is 3 feet per second.
