SOLUTION:
Case: Rate of change. Also called slope (or gradient)
Problem description: The change of d with respect to t is described as every 3 units increase in t leads to a corresponding 8 units increase in d.
Final answer:
Rate of change is caculated as:
[tex]\begin{gathered} \text{Rate of change= }\frac{\Delta d}{\Delta t} \\ \text{Rate of change= }\frac{8}{3}\text{ OR }2\frac{2}{3}\text{ OR 2.67 (approx)} \end{gathered}[/tex]
