Answer:
[tex]3\frac{3}{7}\text{ hours}[/tex]
Step-by-step explanation:
Given,
The south side band can march [tex]1\frac{3}{4}[/tex] miles per hour,
That is, the speed of the band = [tex]1\frac{3}{4}[/tex] miles per hour,
The distance of route = 6 miles,
So, the time taken by band to parade in a route = [tex]\frac{\text{The distance of route}}{\text{speed of band}}[/tex]
[tex]=\frac{6}{1\frac{3}{4}}[/tex]
[tex]=\frac{6}{\frac{7}{4}}[/tex]
[tex]=\frac{24}{7}[/tex]
[tex]=3\frac{3}{7}\text{ hours}[/tex]
First option is correct.
