Lately I've been thinking about this stupid thing and it's been bugging me more than it should.
Basically lets say Im watching a 10 minute video. If I watch it at 1.25x speed, will be over in 7 min 30 sec if I watch it at 1.5, speed, will it be over in 5 mins? But then watching it in 2x speed = done in 5 mins, but isn't 1.5x speed = 50% of 10 mins which = 5 mins which = 1.5x speed done in 5 mins? Help me please I'm retarded.

Flip over this fraction and multiply it by the video length. The result is the time it will take to watch the video at the given speed.
