Initial data: H (initial height from which the parachutist descended uniformly) = 446 m; t (duration of descent) = 2 min 5 s.

SI system: t = 2 min 5 s = 2 * 60 + 5 = 125 s.

The skydiver’s speed can be calculated using the formula: V = S / t.

Let’s calculate: V = 446/125 = 3.568 m / s or 12.8448 km / h.

Answer: The speed of the parachutist is 3.568 m / s.
