Africa and South America are 4,000 km apart. If the plates move away from each other at a rate of 30 km per 1 million years, how long would it take for them to travel 4,000 km?
Rate = Distance ÷ Time Distance = Rate ÷ Time Time = Distance ÷ Rate
The subject is science I just cant find it-
Answer:
The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr. Some sources state that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while others say that plates, in general, travel from 5 to 10 cm/yr.

The Eurasian Plate is moving away from the North American Plate at a rate the is about 3cm per year. That is about the same rate at which your fingernails will grow.

The distance from New York to London is in 3459 miles (5567 km). What will the distance be in 5 million years?.
