In 10 seconds the surface of the earth at the equator has moved 4600 meters. How far has the surface moved in 150 seconds?

Answer 1

To find out how far the surface has moved in 150 seconds, we can set up a proportion:

x/150 = 4600/10

Cross-multiplying, we get:

10x = 150 * 4600

Dividing both sides by 10, we get:

x = 150 * 4600 / 10

Calculating the right side of the equation, we have:

x = 150 * 4600 / 10 = 69,000

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