Answer:
time for 1 cubic kilometer of ice to move  is 2.28 years
Step-by-step explanation:
Given data
cross-sectional area A = 600,000 square meters
velocity v = 2 m per day
to find out
How long will it take for 1 cubic kilometer of ice to move
solution
we know flow rate that is = area × velocity
so flow rate Q = 600000 × 2
flow rate = 1200000 m³/ day
we want time for ice move 1 cubic kilometer
so
time = 1 cubic kilometer  / 1200000 m³/ day
time = 1 × [tex]10^{9}[/tex] m³  / 1200000 m³/ day
time = 833.333 days  =  2.28 years
so  time for 1 cubic kilometer of ice to move  is 2.28 years
