Question 9349: I need help in figuring out this problem
A Child walks along a river bank and a friend rafts on the river. The rafting friend starts from the same point as the walker but leaves an hour later. If the walker's speed is 3mph and the rafter's speed is 9 mph, how far will they have traveled before the rafter catches up to the walker?

If the child leaves at 1:00 p.m., then at 3:00 p.m. he will have gone 6 miles.
If the rafter leaves at 2:00 p.m., then at 3:00 he will have gone 9 miles.
The rafter would pass the child in his first hour of paddling. At 2:30 p.m.
they would be at the same point. Draw out a simple line graph to plot both
of their courses. My drawing below doesn't line up right on my edit screen, but the 4.5
distances should line up:
Child 0 3 4.5 6
rafter 0 4.5 9
