When Elvis swims with the current, he swims 18km in 2 hours. Against the current, he can swim only 14km in the same time. How fast can Elvis swim in still water and what is the rate of the current? Solution D=RT R=D/T R=18/2=9 KMH WITH THE CURRENT. R=14/2=7 KMH AGAINST THE CURRENT. (9-7)/2=2/2=1 KMH IS THE SPEED OF THE CURRENT. PROOF: 9-1=8 SWIMMER\'S SPEED. 7+1=8 DITTO.
