Answer:
[tex]\texttt{Time taken to travel 1 mile}=\frac{4}{127}hours[/tex]
Step-by-step explanation:
Graham drove 42 1\3 miles in 1 1\3 hours.
[tex]\texttt{Distance drove by Graham =}42\frac{1}{3}=\frac{42\times 3+1}{3}=\frac{127}{3}miles[/tex]
[tex]\texttt{Time taken =}1\frac{1}{3}=\frac{1\times 3+1}{3}=\frac{4}{3}hours[/tex]
We need to find how many hours did he take to drive one mile,
[tex]\texttt{ He travels }\frac{127}{3}miles\texttt{ in }\frac{4}{3}hours[/tex]
Time taken to travel 1 mile is given by
[tex]t=\frac{4}{3}\times \frac{3}{127}=\frac{4}{127}hours[/tex]
[tex]\texttt{Time taken to travel 1 mile}=\frac{4}{127}hours[/tex]
