The speed of a boat in still water is 10 mph. It travels 24 miles upstream and 24 miles downstream in 5 hours. What is the speed of the current?
Solution:
Of course this involves D = rt.
Upstream (boat):
D = 24 miles
rate = 10 mph
Downstream ( boat):
D = 24 miles
rate = ?
Total time of trip 5 hours.
What is the equation set up for this problem? Can I say we have a system of linear equations in two variables?
