The graph shows the elevation of a deep-sea diver in relation to minutes passed. Using any two points on the graph, what is the rate of change in the diver’s elevation?

Question

_feet per minute

Answer 1

To find the rate of change in the diver's elevation, we can calculate the slope of the line between two points on the graph.

Let's choose two points: (5 min, 100 feet) and (10 min, 200 feet)

The change in elevation is 200 feet - 100 feet = 100 feet
The change in time is 10 min - 5 min = 5 min

Therefore, the rate of change in the diver's elevation is:
100 feet / 5 min = 20 feet per minute

So, the rate of change in the diver's elevation is 20 feet per minute.
