Andromeda is a "close by" or "neighborhood" galaxy; it is generally believed to be about 2.2 million light years away. In terms of the universe, this truly is "very close by". How far is 2.2 million light years? For starters, the light that you see from Andromeda tonight has been on its journey for 2.2 million years. Had you been around 2.2 million years ago, the sky as we know it today would be largely unrecognizable (due to stellar motion). None of the familiar constellations would look as they do today.
To answer your question:
Most people today drive on the freeway (in the US anyway) at about 70 mph despite a posted speed limit of 55 mph. Let's say you had a really fast car, a car similar to one used in NASCAR racing. Such a car can manage a speed of 200 mph. If you were to take this car, and drive it at full speed continuously (we'll assume no refueling or maintenance stops are necessary), how long would it take to reach the Andromeda Galaxy? Answer: about 7.36 trillion years, which is about 1600 times older than our solar system! So, the speed at which some of the fastest cars can travel is absurdly inadequate for intergalactic travel...

The Andromeda Galaxy , also known as Messier 31, M31, or NGC 224; older texts often called it the Andromeda Nebula) is a spiral galaxy approximately 2.5 million light-years away in the constellation Andromeda.
So if we travel by speed of Light it will take 2.5 million years to reach to Andromeda.
Although now it's a proven fact that objects can travel faster than light( atleast 7 times).

Well obviously that depends on how fast you are traveling. the Andromeda galaxy is approximately 2 million light years away. So if you were traveling a the speed of light (which is impossible) it would take 2 million years to get there. Needless to say you would not survive the journey.

The Andromeda Galaxy is about 2.2 million light years away from ours. So if you're travelling at the speed of light, you'll reach there in 2.2 million years.

Depends on the car you're driving and how fast it's moving.

And don't leave during rush hour, man those queues suck.

100,00 light years.
