A question of "averages" for you;

2 towns are 50 miles apart, you wish to average 50mph for a return journey.
At the start of the trip you get stuck behind a funeral procession & so maintain 25 mph all the way to the town. What speed must you come back at to average 50 mph for the whole trip there & back?

According to the above logic it would be 75mph. do you agree?

I dont.
