The Whitney Glacier on Mt. Shasta is 3.9 km long, has an accumulation area of 0.75 km², and an ablation area of 0.85 km². The average accumulation rate is 4 m/yr. At its equilibrium line altitude (ELA) of 3,300 m elevation, the glacier's width is 300 m, its depth is 50 m, and its slope is 15°. Ice has a density of 900 kg/m³. 1. What is the steady-state flux of ice at the Whitney Glacier's ELA to the nearest m³/yr? 2. What is the glacier's average ablation rate to the nearest tenth of m/yr? 3. Assuming the Whitney Glacier has a rectangular cross section at its ELA, what is the average ice velocity at the ELA to the nearest m/yr?

Please help me with solving them using geology formulas not explanation paragraph. 

The Whitney Glacier on Mt. Shasta is 3.9 km long, has an accumulation area of 0.75 km², and an ablation area of 0.85 km². The average accumulation rate is 4 m/yr. At its equilibrium line altitude (ELA) of 3,300 m elevation, the glacier's width is 300 m, its depth is 50 m, and its slope is 15°. Ice has a density of 900 kg/m³. 1. What is the steady-state flux of ice at the Whitney Glacier’s ELA to the nearest m³/yr? 2. What is the glacier’s average ablation rate to the nearest tenth of m/yr? 3. Assuming the Whitney Glacier has a rectangular cross section at its ELA, what is the average ice velocity at the ELA to the nearest m/yr? 4. What is the shear stress at the bed of the Whitney Glacier at its ELA, to the nearest kPa?
