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
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.
The equator of the Earth is 24,000 miles long, and it takes the Earth 24 hours to complete one rotation. To calculate the speed at which you would be moving, even if you stood still, you need to divide the distance traveled (24,000 miles) by the time taken (24 hours).
The formula to calculate speed is:
Speed = Distance / Time
Using this formula:
Speed = 24,000 miles / 24 hours
Simplifying this equation:
Speed = 1,000 miles per hour
Therefore, the correct answer is D: 1,000 miles per hour.
