The excursion boat travels 35km upstream and then returns to its starting point. The entire trip(both ways) took 4 hours and 48 minutes. If the speed of the boat in still water is 15km/hr and the current is 2.5km/hr how much longer is the trip upstream than the trip downstream. and
It takes a motorboat 50 minutes to travel upstream a distance of 10 miles, and 30 minutes to travel the same distance downstream. Find the rates, in miles per hour, of the boat in still water and of the current.

Thelime contains the point(-3,0) and parallel x-3y=3( show all work)
