5% is pretty steep, I wouldn’t be surprised if one could reach 30 kph without pedaling at all.
Technically you can reach that with any amount of drop per distance where the speed gain exceeds drag as long as you don’t specify how long the incline is.
Thankfully Amsterdam isn’t the first city to do this and most of it is also limited to 30 kph anyway, so we actually this will work out fine.

That’s the question.
