Explanation:

Step1: Convert time to hours

Since 1 hour = 60 minutes, 40 minutes $=\frac{40}{60}=\frac{2}{3}$ hours.

Step2: Use speed - distance formula

The formula for speed $v$ is $v=\frac{d}{t}$, where $d$ is distance and $t$ is time. Given $d = 30$ miles and $t=\frac{2}{3}$ hours. Then $v=\frac{30}{\frac{2}{3}}$.

Step3: Calculate the speed

$v = 30\times\frac{3}{2}=45$ mph.

Answer:

45
