Time is not the issue.
Answer this riddle:
If you go 15mph for 1 mile and 45mph for 1 mile, what is your average SPEED in MPH for the two mile trip ?

Does that include the effect of African or European Sparrows?

its not asking for the average speed. its asking for the speed for the second half of the trip to be averaged with the first half of the trip to complete the trip at an average of 30 mph. An average of 30 mph means you you complete the ENTIRE trip in 4 minutes. it takes you 4 minutes to do the first half, so there is no time left to do the second part.

The answer is: "speed" is not velocity, NOR was the problem framed in terms of speed; it was framed, very specifically (with a bit of deliberate obfuscation, I grant you) as a conditional problem in computing necessary velocity.
Your riddle does not resemble the problem posed at all: the problem stipulates that the vehicle in question has already traveled 1 mile, while your riddle is completely a priori.
Tch, tch. Any time someone speaks of velocity, time is DISTINCTLY part of the issue. Re-take Physics 101, wherein you will be sharply disabused of any notion to the contrary.
