Question

divide. if the southside band can march 1 3/4 miles per hour, how long will it take them to parade along a 6-mile route? 3 3/7 hours 10 1/2 hours 8 hours 6 3/4 hours

Answer 1

3 3/7 hrs (or 24/7 hrs)

1 3/4 miles/hr
7/4 miles/hr
6 = 6/1
6/1 /(7/4)
6/1*(4/7)
24/7 = 3 3/7

Answer 2

`3(3)/(7)\text{ hours}`

Explanation:

Given,

The south side band can march
`1(3)/(4)` miles per hour,

That is, the speed of the band =
`1(3)/(4)` miles per hour,

The distance of route = 6 miles,

So, the time taken by band to parade in a route =
`\frac{\text{The distance of route}}{\text{speed of band}}`

`=(6)/(1(3)/(4))`

`=(6)/((7)/(4))`

`=(24)/(7)`

`=3(3)/(7)\text{ hours}`

First option is correct.
