    1/250 W/m² or 0.004 W/m² or 4 mW/m²

    Step-by-step explanation:

    The cargo worker is (50 m) / (1 m) = 50 times the reference distance. The intensity varies as the inverse of the square of the distance, so will be ...

    (1/50) ² * (10 W/m²) = 10/2500 W/m² = 1/250 W/m²

    This might be more conveniently written as 4 mW/m².
