Answer 2

Answer and Step-by-step explanation:

`Let's~solve~your~problem!`

Formula :

`speed=(distance)/(time)`

Solving for time:

`Time~taken~to~cover~40~miles~on~local~ roads~= (40)/(20) = 2~hours`

`Time~taken~to~cover~180~miles~on~the~highway~=`
`(180)/(60)=3~hours`

`Total~Time~=~5~hours`

Solving for distance:

`Total~Distance=40 + 180 = 220`

Average speed:

`(Total~distance)/(Total~time) = (225)/(5) = 44~miles~per~hour`
