Question

A valley glacier has a cross-sectional area of 600,000 square meters and a flow velocity of 2 m per day. How long will it take for 1 cubic kilometer of ice to move past a given point?(Show your work or explain your answer completely to receive full credit)

Answer 1

time for 1 cubic kilometer of ice to move is 2.28 years

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 ×
`10^(9)` 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
