Assume that the equator of the Earth is 24,000 miles long (that’s its circumference). Now, pretend that you are standing somewhere on the equator, such as in the country of Ecuador. Now, if the Earth turns once, completely, in 24 hours, then, how fast would you be going (in miles per hour), even if you just stood still?

Choose the best answer from the options below:
A zero
B 100
C 500
D 1,000
E 10,000

1 answer

The length of the equator is 24,000 miles, and it takes 24 hours for the Earth to complete one rotation. Therefore, if you stood still on the equator, you would be covering the distance of the equator in 24 hours.

To calculate the speed, we can divide the distance traveled (24,000 miles) by the time taken (24 hours):
Speed = Distance / Time = 24,000 miles / 24 hours = 1,000 miles per hour

Therefore, the correct answer is D) 1,000.
