Question 9:
Here's a question that may
not need x or y, but good algebra logic is
needed.
It comes from a Tri-County
Tech. book in South Carolina.
The
speed of a river is 5 mph. If a boat travels 98
miles downstream in the same time it takes to
travel 49 miles upstream, what is the speed of
the boat in still water?
