No, that's not how the math works out. Doubling your speed only halves the time it takes.

If I'm driving 100km and I drive 120km/h

No, you should actually follow through with the math. I used a simple example in hopes it would be obvious.

At a distance of 100km it take 60 minutes at 100kph. Change that to 120kph and it takes 50 minutes. 20% quicker would be 48 minutes. 20% faster gets you there 16.666% quicker.
