Refer to the diagram shown below.

Assume that air resistance is ignored.

Note:

The distance, h, of a falling object with initial vertical velocity of zero at time t is

h = (1/2) gt²

where

g = 9.8 m/s²

The initial vertical velocity of the supplies is 0 m/s.

It the time taken for the supplies to reach the ground is t, then

(50 m) = (1/2) * (9.8 m/s²) * (t s) ²

Hence obtain

t² = 50/4.9 = 10.2041

t = 3.1944 s

The horizontal distance traveled at a speed of 100 m/s is

d = (100 m/s) * (3.1944 s) = 319.44 m

Answer: 319.4 m (nearest tenth)
