D=rt
when the distances traveled are the same, they are at the same place (caught up)
the time that the cyclist travels in that distance is t
the times that the hiker travels in that distance is t+1 (1 hour head start)
if hiker rate=3mph
and cyclist=3+6=9mph, then find the distance
hikerdistance=hikderdistance
3(t+1)=9t
3t+3=9t
minus 3t
3=6t
divide both sides by 6
1/2=t
the answer is 1/2 hour after the cyclist left, or 1 and 1/2 hour after the hiker left
