Keep messing this one up.....thanks for the help.. Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! b=3h biker travels 3 times faster than the hiker
3h*3=h*3+24 in 3 hours the biker will be 24 miles ahead of the hiker.
9h=3h+24
9h-3h=24
6h=24
h=4 mph. speed of the hiker.
b+3*4
b=12 mph. for the biker.
proof:
3*4*3=4*3+24
36=12+24
36=36
