A plate moves 200m in 10,000 years. what is the rate in cm/year
algol13

Answer:

Rate = 2 cm/year

Explanation:

It is given that, a plate moves 200m in 10,000 years. We need to find its rate in cm/year.

We know that, 1 m = 100 cm

200 m = 200 × 100 cm

= 20000 cm

Its rate is given by :

R=\dfrac{20000}{10,000}\\\\R=2\ cm/year

So, the plate is moving at a rate of 2 cm/year.
