it is given keimon travels 28 miles in 36 minutes
so its speed is = distance/ time
= 28 / 36
= 7/9 miles per minute
the time to travel 38 miles will be = distance/ speed
[tex]=\frac{38}{\frac{7}{9}}=\frac{38\times9}{7}=\frac{342}{7}[/tex]so the time is 342/7 minutes
now we will convert it into hours
60 minutes = 1 hours
1 minute = 1/60 hours
342/7 minutes =
[tex]\begin{gathered} =\frac{1}{60}\times\frac{342}{7} \\ =0.81 \end{gathered}[/tex]it will take 0.81 hours to ride 38 miles.
