A fishing boat travels 1 mile up the Paddywock River and then returns.  The current in the river is 3 mph.  The total trip time is 48 minutes.  Assuming the boat travels at a constant rate, find the speed of the boat.

3. Rational Functions:The simple equation for the time taken for an object moving at a speed, , (km/hr) over a distance, d (km) is given by t (hr) The objective is to apply this to a simple example of motion A boat can travel at 32 km/hr in still water. It travels on a river, going 150km upstream against the current, then returns to its starting location. Given that the boat is travelling at marimum speed the whole way, the total trip time is What is the speed of the current, c? (in km/hr) Hint: tTOTAL=tUPSTREAM + t DOWNSTREAM 6 marks

A boat travels 12 miles upstream in 3 hours. Going downstream, it can travel 42 miles in the same amount of time. Find the speed of the current and the speed of the boat in still water. What is the speed of the current?mph What is the speed of the boat in still water?mph
