The time the package travels horizontally is equal to the time it takes to hit the ground. This can be calculated using:

s = ut + 1/2 at²; u is 0

480 = 4.9t²

t = 9.90 seconds

Horizontal distance = horizontal speed x time

The speed will be converted to m/s from km/h

= 180 km/hr x 1000m/km x 1hr/3600 seconds x 9.90 seconds

= 495 m
