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? show your work
A 3.07
B 6,900,000
C 69,00
D 306.67
To find the distance the surface has moved in 150 seconds, we can use the proportion:
10 seconds is to 4,600 meters as 150 seconds is to x meters.
We can set up the proportion:
10/4,600 = 150/x
To solve for x, we can cross-multiply:
10x = 150 * 4,600
10x = 690,000
Dividing both sides by 10:
x = 69,000
Therefore, the surface of the earth at the equator has moved 69,000 meters in 150 seconds.
The correct answer is C) 69,000.
