A shark can swim at a rate of 16 feet per second and a tuna can swim at a rate of 13.6 feet per second. The shark sees a tuna 100 feet ahead of him and starts the chase. (a) Draw a SF map and a BOTG for this situation. (b) Use your graph to give an estimate the time it takes for the shark to catch the tuna and the distance that the shark will have traveled at that point. (c) Indicate the initial values of the stocks and the values of any flow or converted in your map. (d) Calculate how long it will take the shark to catch the tuna.
