Is there any wind? What's the elevation and barometric pressure (air density)? What's the coefficient of friction on the bullet's cross-section? How many rotations per minute is the bullet turning? Will it flip and fall point down at the top, or sideways, or tail-first? If you're looking for a "real world" answer, there's a LOT of information missing, a LOT of variables...
If you're thinking in a vacuum, no wind, basically a physics class problem, it'll be about 50 seconds, and hit a peak altitude of about 3062.5 meters before falling.

50 seconds
Does a 22 cal bullet rise at 75 yards?
no! all bullets fall. A bullet dropped from the edge of a table at the same time a bullet at the same table height leaves a barrel hits the ground at the same time.
Does a bullet shot from a gun undergo any acceleration after it leaves the barrel?
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
How does a bullet leave a gun?
A bullet leaves a gun barrel because it is forced out by the pressure of burning gasses.
What is a muzzle for a gun?
It is the opening at the front of the gun where the bullet leaves the barrel.
What is the difference between rifled and smoothbore?
Smooth-bore is like a tube, think of it as a straight pipe. Rifling is a pipe with grooves swirling around on the inside of the pipe. This makes the bullet spin as it travels down and leaves the barrel. This spinning makes the bullet fly straighter than a bullet fired from a smooth-boar barrel.
What is a muzzle in a gun?
It is the hole at the front end of the barrel where the bullet leaves the gun.
What would cause a bullet to explode after it leaves a rifle barrel?
how fast it is going
Does a shotgun sabot slug rise after it leaves the barrel of the gun?
No, a sabot slug does not rise after it leaves the barrel of a gun. No bullet rises after it leaves the barrel of a gun. It always falls from the line of sight of thebarrel. All firearms have to be "sighted in" a bit high to hit a target downrange. At close range, there is little time for a bullet to drop and hit "low" on the target. Down range, however, the drop is more significant. The more time a bullet is in flight, the more it drops below the line of sight of the barrel. But a bullet always begins to drop below the line of sight of the barrel after it leaves the muzzle. Always.
What causes a bullet to rotate on exit?
What causes it to rotate is the rifling in the barrel. What causes it to continue to rotate after it leaves the barrel is centrifugal force.
What causes a bullet to spin when fired?
Rifling in the barrel is actually grooves cut into the barrel by the manufacturer to cause the bullet to spin as it leaves the barrel. Before rifling the bullets would tend to tumble when they left the barrel causing them to have shorter range and be less accurate.
A rifle is shot straight up and the bullet leaves the barrel at a speed of 245 ms How long will it take the bullet to hit the ground?
We're going to ignore air resistance.Time the bullet spends on the way up = 245/9.8 secondsTime it spends on the way down to the same elevation as the muzzle = another 245/9.8 secondsTotal time to return to the elevation of the muzzle = (2 x 245 / 9.8) = 50 seconds.From there, we don't know how high the muzzle of the gun is above the ground, sowe can't calculate the duration of the extra little bit until the bullet hits the ground.
