Answer :
Given the formula;
[tex]\begin{gathered} \text{Distance}=\text{Speed}\times time \\ D=s\times t \end{gathered}[/tex]Then, the time taken is the ratio of the distance and the speed. That is;
[tex]t=\frac{D}{s}[/tex]But Deandre drives 203 miles at a constant speed of 58mph. Then, the time it took would be;
[tex]\begin{gathered} \text{Where;} \\ d=203\text{miles} \\ s=58\text{mph} \\ t=\frac{203}{58} \\ t=3.5 \end{gathered}[/tex]Hence, note that the unit of time in the problem is hour. Thus, the time taken to drive 203 miles at a constant speed of 58mph is 3.5hours
