The only solvable equation would be that it doesn't matter. The G force from instantaneous acceleration would be fatal. (0-88mph in .5s would be more than fatal. Faster would just leave you as a puddle). Otherwise, you need to factor in the time from 0-88 and 88-0, which will make the time longer.

He will arrive at 1205 hrs..

SO......I took @tbg0519 challenge on this one. @buckbuck I owe you an apology. Once I took into account acceleration, the time jumps to 12:05:36.929......which rounds back UP to 12:06. Sorry sir.

Here's the math if anyone is interested.......and yes I was bored on a Friday afternoon :D

You definitely are in need of some sort of therapy. :)
I mean.....Maybe.......I did mess around with the accel and decel numbers to find something realistic that a math teacher might drive. Those assumptions can really swing the math a few thousandths either way.....Yea, I probably need help at some level
 
I came up with 35.4 minutes… I didn’t, nor could I do the deep dive that @2kwik4u did… I took the word problem at its face value… leaving at 1130hrs at 88 mph. Blame the NERC RC test ….

52miles / 88 mph=.590 hrs
.590x60mns=35.454545, so I guess I should have rounded up to 35.5 minutes + 1130 to =1205hrs.

Fun stuff!
 
Constant acceleration to 88 mph? Very disappointed in you. ;) (BTW, The R1T 0-90 is ~7 sec)
Yea, Math Teacher probably can't afford a Rivian (before his move to the private sector that is), but can probably do the Diff Eq to account for non-linear acceleration.

Just occurred to me there's got to be some philosophy to go with this math.......Do we round time? When is the next minute said to begin? If we round, then this minute accounts for the 50% before and 50% after it's exact time. If we don't round, then we are forced to use the lower bounds as the :05 minute has not completed itself yet, and we have not yet begun the :06 minute when he arrives. This a stopwatch (truncated to just minutes) would still say 12:05. So, perhaps @buckbuck and I should settle this over a pint as we discuss the nuances of what constitutes a minute?!?!

So much math! I had to scroll back up to the top of page to see what thread I was reading! :p
