How do I use delta time to measure the time since I pressed a button and held it?

Isn’t this the same as you asked before?

How do I create movement with acceleration?

I want to let the player (a B E A N) first move slowly (accelerate it like a car) and then let it move at a constant speed and in the end let it break like reverse acceleration. How is this possible? Thanks in advance
