How i can know the range missiles? I have been with Velocity X flight time but its wrong.
Velocity missil : 4500m/s Flight time: 10s
Range: 45 km? no, about 40km. what is the equation for the range?

There is the idea that missiles take time to accelerate to full speed, and they come in at their target at an arc or take a small little loop before hitting their target. This means that the theoretical max range is not correct. If you want a better number, just multiply your final answer by .9. So 45km is actually 40.5km range which is what you have observed.

Don't forget that to include target motion too. If the target moves away from your starting position (when you fired the missile) that has to be added to range. Vice versa for when someone is chasing you, makes your effective range longer.

This had added range from you to the target, not extra range to the missile.

I have been spoken with more people and the answer its very difficult. In other example,
Velocity = 5250 Flight time = 15
theorically = 78750. With your equation = 70875. This guy say that he hit about 75km

Never beleive this guy :)
As the posters said before it's depending if the target is moving to you, if the target is moving away, are you moving yourself, does the target have a transversal on you etc.

Target is a structure and my ship is stopped.

Missile acceleration to top speed is losing you that distance then.
Nobody except CCPs knows the exact equation for missile range, but you can calculate your maximum theoretical range, then as a rule of thumb, take off 10% for manoeuvring and acceleration effects.
If you want to calculate it down to the last exact metre, then you'll have to experiment for yourself.

You forgot about the relative velocity of you to the target. This can increase or decrease your effective range.
Example: after 10 seconds the missile blows up. It can travel 45 km. If you were being chased by a cruiser doing 100 m/s, and running away at 200 m/s when you fired, you effectively slowed the missile to 4400 m/s so it has a range of 44 km. Chase the cruiser and you gain 1 km.
Missile acceleration time has a effect too, based on its mass and inertia modifier.
I don't know the exact formula. If I can't hit something I move closer

This is the wrong way round.
The missile has its own propulsion system and its range is calculated from where you fired as it becomes independent of your ship. If you were being chased by a cruiser, then you'd gain approximately 1km extra range as after 10 seconds the cruiser is 1km closer to where you fired the missile from.
If you were chasing the cruiser, then you'd lose 1km as the cruiser is now further away from where you fired the missile from.
