Maths issue

Pacific plate is moving at a rate of 1100 cm every million years, what is that in cm a year? i thought i just divided it 1100 by a million but that does not seem to get an answer that looks right

 

[Thorwyn]

Why not?

1100 / 1000000 = 0,0011

so 0,0011 cm/year

That´s 0,11 in 100 years, 1,1 in 1000 years and 110 in 100.000 years

sadly its ment to be 8.9 or somthing, to hell with it, i can only work with the data they gave me, the graphs dont lie

 

[tris-]

how the hell can it be 8.9?!

8.9 is clearly bollocks given the numbers 1100 and one million. Who did the graph ? Peter Griffin ?

The whole thing looks bollocks. 250 million years ago all the continents were in one big blob. According to that they would be 2.75km away from each other if moving at that speed but we know they are thousands of kilometers apart.

the movement speeds have changed over time. when pangaea was breaking up into the continents we know these days, some of the plates were going as fast as 15 cm a year.
