I know that is a very, very trivial question... But I'd be super thankful for any help.
Lets say you have three values where each describes the velocity of a car.
50 kmh, 100 kmh, 150 kmh
I just want to double check that it is correct to say that:
50 kmh is 50 % slower than 100 kmh, and 150 kmh is 50 % fast than 100 kmh.
My doubt is coming from the fact that while 50 kmh is half of 100. 150 is not the double. Like I said, its probably very trivial...
