Although the post does not contain any question, the problem may have two answers. 

One answer is  %281%2F2%29%2A%2833%2F4%2B33%2F5%29 = 7.43  km/h  (rounded as requested).


The other answer is  %281%2F2%29%2A%2833%2F4-33%2F5%29 = 0.83  km/h  (rounded as requested).


Had you put your question in the post, I'd explain you what these numbers mean.


But it looks like, you are not too interested in it.
