Question

a plate moves south at a rate of 2 cm/year. how many meters south from its original location will the plate be in 4,000 years?
○ 8,000 meters south
○ 4,000 meters south
○ 200 meters south
○ 80 meters south

Explanation:

Step1: Calculate total centimeters moved

The plate moves at 2 cm/year for 4000 years. So total distance in centimeters is \( 2 \, \text{cm/year} \times 4000 \, \text{years} = 8000 \, \text{cm} \).

Step2: Convert centimeters to meters

Since 1 meter = 100 centimeters, we divide the total centimeters by 100. So \( \frac{8000 \, \text{cm}}{100} = 80 \, \text{meters} \).

Answer:

80 meters south (corresponding to the option "80 meters south")
