With the ability to measure the motion of land masses, continental drift has become an established fact. The North American and European continents are drifting apart at a rate of about 3 cm/y. At this rate how long will it take them to drift 850 km further apart than at present?

Thank you for the opportunity to help you with your question!

1 km = 1000 m = 1000*100 cm=100000 cm


rate of drifting = 3cm /yr

length of drift =850 km =850*100000 cm

               time =850*100000/3

                       =28333333.33 yrs.

Please let me know if you need any clarification. I'm always happy to answer your questions.
