A motorboat travels 168 kilometers in 4 hours going upstream. It travels 280 kilometers going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current

168 / 4 = 42 kph - its speed upstream

280 /4  =70 kph - its speed downstream

 

[42  + 70] / 2 =56 kph - its speed in still water

[70 - 42] / 2  =14 kph - the speed of the current.
