Question

Can someone answer this for me?

Answer 1

`3(3)/(8) = (8(3) + 3)/(8) = (27)/(8)`

`5(1)/(4) = (4(5) + 1)/(4) = (21)/(4)`

`(21 (miles))/(4)` ÷
`(27 (miles))/(8 (hour))`

=
`(21 (miles))/(4) * (8 (hours))/(27 (miles)) = (21(8)hours)/(4(27)) = (42)/(27)hours`

`(42)/(27) hours` =
`(14)/(9)= 1(14-9)/(9) hours = 1(5)/(9)hours`

Answer:
`1(5)/(9)hours`
