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
