Answer and Step-by-step explanation:

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

<em><u>Formula : </u></em>

<u></u> $speed=\frac{distance}{time}$

<em><u>Solving for time:</u></em>

$Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20} = 2~hours$

$Time~taken~to~cover~180~miles~on~the~highway~=$ $\frac{180}{60}=3~hours$

$Total~Time~=~5~hours$

<em><u>Solving for distance:</u></em>

<em><u /></em> $Total~Distance=40 + 180 = 220$ <em><u /></em>

<em><u /></em>

<em><u>Average speed:</u></em>

<em><u /></em> $\frac{Total~distance}{Total~time} = \frac{225}{5} = 44~miles~per~hour$ <em><u /></em>
