Answer:
Africa and North America have moved away from each other for 2 × 10⁸ years.
Meaning they were right next to each other 200 million years ago.
Explanation:
Given,
- Africa and North America are moving away from each other at a velocity (rate) of 3 cm/year.
-Africa and North America are presently 6000 km apart.
Speed = distance/time
Time = distance/speed.
Distance = 6000 km = 6000000 m
Speed = 3 cm/year = 0.03 m/year
Time = 6000000/0.03 = 2 × 10⁸ years.
