SUMMARY
The minimum power required for a truck weighing 30,000 Newtons to climb a hill of 160 meters length and 800 meters height over a duration of 480 seconds is calculated using the formula P = W/t. The correct calculation yields a minimum power of 1.5 x 10^5 Watts, which represents the power needed to overcome gravitational force without accounting for additional factors such as friction or air resistance. The term 'minimum' indicates that this value is the baseline power required under ideal conditions.
