I have a table in org-mode with time needed to travel from A to B an the
number of km. I would like to get the average speed. How do I convert a
time? For example 0:45 becomes 0.75.
How do you know that 0:45 becomes 0.75?

How did you do it?
I did not. I want. 0:45 is three quarters of an hour, so in mathematical
notation 0.75.

Something like this could be helpful:

(defun time100(time)
  (let ((timelist (split-string time ":")))
    (+ (string-to-number (car timelist))
       (/ (string-to-number (cadr timelist))
