1 century = 100 years. 4 centuries = 400 years. Motion of glacier = 400 years x 43.0 meters/year = ????.? meters (you can do the rest).

Given 4 centuries, start there and apply converters canceling units.

4 cen (100yr/century) (43.0 m/year) = 17200 m

More correctly 1.72 x 10⁴ m

We learned to do multiplication in primary school. 43*400 . As the 400 has only one significant digit it can be done in one's head in a couple of seconds.

We know that

1 century = 100 years

So, 4 centuries = 400 years

Now, 43 meters per year x 400 years

= 739,600 meters

Thus, if a glacier moves a the rate of 43.0 meters per year, it will move 739,600 meters in four centuries

In four centuries the planet will be too hot to support glaciers, so there's your answer. If they say my answer is wrong you can call them a science denier.
