To find out how far the surface of the earth at the equator has moved in 150 seconds, we can use a simple proportion based on the distance moved in 10 seconds.
If the surface moves 4,600 meters in 10 seconds, we can calculate the distance moved in 150 seconds with the following steps:
-
Calculate the speed (meters per second): \[ \text{Speed} = \frac{4,600 \text{ meters}}{10 \text{ seconds}} = 460 \text{ meters/second} \]
-
Now, calculate the distance moved in 150 seconds: \[ \text{Distance} = \text{Speed} \times \text{Time} = 460 \text{ meters/second} \times 150 \text{ seconds} = 69,000 \text{ meters} \]
Thus, the surface has moved 69,000 meters in 150 seconds.
The correct response is: 69,000 meters.
