Horizontal distance of horizontally fired projectile

[physicsman2]

Homework Statement

If a plane 8500m in the air is traveling with a horizontal speed of 483km/hr when a capsule is released, what is the horizontal distance between the point at which the capsule is released and the point at which the capsule strikes the ground.

Homework Equations

vertical displacement = 1/2(g)(time)^2
horizontal displacement = horizontal velocity(time)
*g=acceleration due to gravity

The Attempt at a Solution

i tried to find the time and multiplied it to the horizontal velocity but i didnt get the right answer

Your approach is OK. You probably didn't convert the speed from km/hr to m/s.

Note: one is in meters and one is in km/hr. Your method is right.
