Question 837259: I need help setting out an equation for the following word problem. "A boat traveled 210 miles downstream and back. The trip downstream took 10 hours. The trip back took 70 hours. What is the speed of the boat in still water? What is the speed of the current?" Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! each way was 105 miles
10*(b+c)=105,
70*(b-c)=105
c = 9/2=4.5, b= 6
Boat in still water goes 6 mph
The current is 4.5 mph
