adjust transition duration according to move distance - html

Question

In my example when a user hovers over a text that is too long for its container
it will start scrolling so the entire content can be read.
My problem is that I don't know how to adjust the transition duration
according to the length of the content.
I want that the text scrolls with a consistent speed across all containers.
