# Run 3ds Max animated train at specific speed in unity

I have a 3d Max exported Train animation which has animated at speed of 1 in 3Ds max Tool. Now, I have to run the animation at specific speed like 160 kilometer per hour (KMPH). I can easily set the animation speed using speed property but how can i form a formula that accurately run the animation at specific speed? Do I need to change in animation in 3d max or i can change it in unity?

I have no knowledge about 3d Max tool but i think that i need to determine that at what speed it is animating in max and that speed how much is equal to a real scenario.
