In 10 seconds, the surface of the Earth at the equator has moved 4,600 meters. How far has the surface moved in 150 seconds?

69,000 meters
3.07 meters
6,900,000 meters
306.67 meters

1 answer

To find the distance the surface of the Earth has moved in 150 seconds, we can use the proportion:

Distance in 10 seconds / 10 = Distance in 150 seconds / 150

Simplifying the equation, we have:

4600 meters / 10 = Distance in 150 seconds / 150

Solving for the distance in 150 seconds, we get:

Distance in 150 seconds = (4600 meters / 10) * 150

Distance in 150 seconds = 4600 meters * 15

Distance in 150 seconds = 69,000 meters

Therefore, the surface of the Earth at the equator has moved 69,000 in 150 seconds.
