If two plates diverge at a rate of 1.3 cm/year, how much farther apart will the plates be after 200 million years?

260,000,000 cm

Explanation:

Given that; if two plates diverge at the rate of 1.3 cm/ year

i.e in 1 year, their rate of divergence = 1.3 cm

after 200 million years , their divergence rate will be;

=  

=  260,000,000 cm

Therefore, their rate of divergence after 200 million years will be 260,000,000 cm.
