Question

A valley glacier has a cross-sectional area of 900,000 square meters and a flow velocity of 3 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

370.37 days or 1.02 years

Step-by-step explanation:

Given : Area = 900,000 m² ; velocity = 3 m/day ; Volume = 1 km³ = 1×10⁹ m³

The flow rate is given by : Q = Area * velocity

Q = (900,000 m²)*(3 m/day) = 2700,000 m³/day

The time required for ice to move past a given point is given by :

t = (1×10⁹ m³) ÷ (2700,000 m³/day)

= 370.37 days or 1.02 years
