The average speed of Earth as it orbits the Sun = 66000 miles/hour (option A).
The average speed is the total distance traveled by the object in a particular time interval.
It is given by the formula:
Average speed = [tex]\frac{Total Distance Covered}{Total Time Taken To Cover The Distance}[/tex]
Now, given:
To find: Average Speed of Earth as it orbits the Sun
Now, we know that average speed= [tex]\frac{Distance}{Time}[/tex]
Thus, average speed of Earth as it orbits the Sun = [tex]\frac{Distance Travelled By Earth In 1 Orbit}{Time Taken By Earth To Complete 1 Orbit}[/tex]
=> Average speed of Earth = [tex]\frac{58 \times 10^{7} miles}{8760 hours}[/tex] = 66210 miles/hour ≈ 66000 miles/hour
Hence, The average speed of Earth as it orbits the Sun = 66000 miles/hour (option A).
