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 distance in cm

Multiply rate by time. $2\times4000 = 8000$ cm

Step2: Convert cm to m

Since 1 m = 100 cm, divide by 100. $\frac{8000}{100}=80$ m

Answer:

80 meters south
