To determine who worked shortest distance, we have to convert all the distance in fraction to decimals
[tex]\begin{gathered} \text{Brad covered 6}\frac{1}{4}\text{ miles } \\ 6\frac{1}{4}\text{ = 6 +}\frac{1}{4}=\text{ 6 + 0.25} \\ 6.25\text{ miles} \end{gathered}[/tex][tex]\begin{gathered} \text{Denim coovered 6}\frac{2}{3}\text{ miles} \\ 6\frac{2}{3}=6\text{ +}\frac{2}{3}\text{ = 6 + 0.67} \\ \Rightarrow\text{ 6.67 miles} \\ \end{gathered}[/tex]From the table, the shortest distance covered is 6.05 miles
And this distance was covered by Charles
