Find area between rate curves - interpretation check

The net rate difference for a water monitoring program is \(r(t)=6t+2\). Find the net accumulated change from \(0\) to \(5\). Enter the requested value and choose the interpretation that matches the result.

Worked practice: result and interpretation

Calculate the requested result first, then choose the interpretation that follows from it.
