The height of the plane delivering a food package to people stranded on an island is 722.2 m.
The time taken for the food package to hit the ground level is calculated as follows;
X = vt
where;
t = X/v
t = 789/65
t = 12.14 seconds
h = ¹/₂gt²
where;
h = (0.5)(9.8)(12.14²)
h = 722.2 m
Thus, the height of the plane delivering a food package to people stranded on an island is 722.2 m.
