You need to provide the units of the bullet speed. Just the number "188" isn't enough.
The same goes for the distance of "88".
The importance of units (dimensions), and how to convert them, is one of the first things you should learn about physics
A hunter aims directly at a target (on the same level) 85.0 away. If the bullet leaves the gun at a speed of 188 , by how much will it miss the target?

A hunter aims directly at a target (on the same level) 85.0 m away. If the bullet leaves the gun at a speed of 188 m/s, by how much will it miss the target?
Calculate the time it takes to travel 85 m. That is just 0.45 s. Then, calculate how much the bullet falls in that time.
Use Y = (g/2)t^2
That will be the miss distance.
Use Y = (g/2)t^2
That will be the miss distance.
