Answer:

66622.653 mi/hr

Explanation:

The average speed at which the Earth rotates around the Sun = 29.783 km/s

1 km = 0.621371 miles

The conversion of s to hr is shown below:

1 s = 1 / 3600 hr

So,

$29.783\ km/s=\frac {29.783\times 0.621371\ miles}{\frac {1}{3600}\ hr}$

Thus,

<u>The average speed at which the Earth rotates around the Sun in miles per hour = 66622.653 mi/hr</u>
