Rates of Hair Loss?

Hello Dr.Rassman!
Thank you for the previous answers! I have another question:

If guy A starts losing his hair when he is 20 and guy B at 27, is it 100% sure that guy A will have less hair than guy B at his 40s? Once again thanks for your time!

If guy A starts out traveling at 55mph from Los Angeles on the 405 freeway going south at 4pm on a Memorial Day weekend in an SUV and guy B starts out traveling at 70mph on the 10 freeway east bound at 5pm on the Friday of Thanksgiving weekend in a Porsche, who will have traveled the farthest by 7pm?

If you can answer that question, then I will attempt to answer yours.

For those of you who can not calculate the math challenge (hey, I can’t either) — I would say that no two people lose hair at the same rate, so time varies with the patient.
