I hope that I am asking this question in the right place, so please
bear with me as a newbie!

I have been asked by a solicitor to find out at what rate the sun sets
in Coventry between 7pm and 8pm on 3rd June.

I guess the question is about angle of elevation above the horizon i.e.
angle of fall per time unit?

It's for a court case up and coming this month, so I would appreciate
some help please.

Thanks
