Answer:
4 h
Step-by-step explanation:
The resting spot was at the 8 mi mark.
When Stacey reached the 16th mile, they had covered
16 mi - 8 mi = 8 mi
They took 2 h for every 1 h, so
[tex]\text{Time required} = \text{8 mi} \times \dfrac{\text{1 h}}{\text{2 mi}} = \textbf{4h}[/tex]
It may be easier to do this calculation on a number line. Each jump of 2 mi represents 1 h, and there are four jumps, so they took four hours.
