# a glacier moves a the rate of 43.0 meters per year. how far will it move in four centuries?

if anyone can help it would be greatly appreciated. thanks in advance

Relevance

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

• This isn't really a physic question...

• 43m/y

1 cent =100y

4 cent=400y

43*400=17.2km

• 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

• d = 43*400/1000 = 17 km (just two sign. digits)

• 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.
