The time required to catch Courtney is $4\text{h}$ .

Explanation of Solution

Given information:

The speed of Courtney is $8\text{miles}/\text{h}$ and the speed of Horacio is $10\text{miles}/\text{h}$ .

The time required to catch Courtney is calculated as,

  $\begin{array}{l}\left(t+1\right)\left(8\right)=\left(t\right)\left(10\right)\\ 8t+8=10t\\ 2t=8\\ t=4\text{h}\end{array}$

Thus, the time required to catch Courtney is $4\text{h}$ .
