[tex]3\frac{3}{8} = \frac{8(3) + 3}{8} = \frac{27}{8}[/tex]
[tex]5\frac{1}{4} = \frac{4(5) + 1}{4} = \frac{21}{4}[/tex]
[tex]\frac{21 (miles)}{4}[/tex] ÷ [tex]\frac{27 (miles)}{8 (hour)}[/tex]
= [tex]\frac{21 (miles)}{4} * \frac{8 (hours)}{27 (miles)} = \frac{21(8)hours}{4(27)} = \frac{42}{27}hours[/tex]
[tex]\frac{42}{27} hours[/tex] = [tex]\frac{14}{9}= 1\frac{14-9}{9} hours = 1\frac{5}{9}hours[/tex]
Answer: [tex]1\frac{5}{9}hours[/tex]
