Hi,

Distance = r*t

rowing downstream (with the current) for five hours. Speed =(12kph + xkph)

Distance =(12k/hr + xk/hr)*5hr



Knowing the speed of the current(k/hr), we would know 'exactly' how far  he traveled.  

For example: if the speed of the current was 3k/hr: speed would be (12+3)kph

Distance = 15k/hr*5hr = 75k              



(kilometer ~ .62 mi)
