Answer:
66622.653 mi/hr
Explanation:
The average speed at which the Earth rotates around the Sun = 29.783 km/s
Also, The conversion of km to miles is shown below:
1 km = 0.621371 miles
The conversion of s to hr is shown below:
1 s = 1 / 3600 hr
So,
[tex]29.783\ km/s=\frac {29.783\times 0.621371\ miles}{\frac {1}{3600}\ hr}[/tex]
Thus,
The average speed at which the Earth rotates around the Sun in miles per hour = 66622.653 mi/hr
