Question

Answer 1

Go on chegg they are good !!

Explanation:

Answer 2

The construction crew took
`3(3)/(8)` days to build
`4(1)/(2)` miles of road.

Therefore, in 1 day, the crew built
`(4(1)/(2) )/(3(3)/(8) )` miles of road

=
`((9)/(2) )/((27)/(8) ) =(9)/(2)times(8)/(27)=(4)/(3)` miles of road

Thus, the required rate is
`(4)/(3)` miles or
`1(1)/(3)` miles per day.
