1)a motor boat can maintain a constant speed of 16km/hr in still water.The boat makes a trip upstream to a certain point in 20min;the return trip takes 15 min. what is the speed of the current?
2) a boat takes 5 hours to make a trip upstream to a camp,on a river that has a current of 3km/hr. It then takes the boat 2.5 hours to make the return trip.How fast did the boat travel relative to the water?
any help would be nice thanks
