Problem on boats and streams
Required help to solve math homework problems
What is the time taken by the boat to go to 68 km downstream, If a boat can travel with a speed of 13 km/hr in still water and the speed of the stream is 4 km/hr?

distance = rate x time 68 km = 17 km/hr x time 68/17 hr = time 4 hrs = time.
