How many years would it take for the glacier to move .74km?

[doggerz]

omg help!

ok ppl I am having trouble with this problem...

A glacier moves with a speed of 41 nm/s. How many years would it take for the glacier to move .74km? answer in units of yr.

ok and this is what I've done...

i changed 41 nm to km which i got as 41*10^-6 ...

and then i divided it by 0.74 and got some weird number like 31536000

ur somebody please tell me how to do it

first of all, a nanometer is 10^-12 kilometers

so the velocity would actually be 4.1*10^-11 km/s

now we convert this into km/h, so:

(4.1*10^-11)*3600 = 1.476*10^-7 km/h

now to get time it would take, we obviously use t = d/v:

t = (0.74)/(1.476*10^-7)

t = 5013550.136 hours

which is approximately 572 years
