You can put this solution on YOUR website!
t = time for the 65mph, 8AM driver to catch to the distance of the earlier, slower driver.

_________________speed___________time___________distance
early slow_______60_____________t+1____________d=60%28t%2B1%29
later fast_______65_____________t______________d=65t
