a cabin cruiser traveling with the current went 120 km in 3 h. Against the current it took 5 h to travel the same distance. please find the rate of the cabin cruiser in still water and the rate of the current.
\n" ); document.write( "---------------------
\n" ); document.write( "With Current DATA:
\n" ); document.write( "distance = 120 km ; time = 3 hr ; rate = 120/3 = 40 km/hr
\n" ); document.write( "-------
\n" ); document.write( "Against Current DATA:
\n" ); document.write( "distance = 120 km ; time = 5 hr ; rate = 120/5 = 24 km/hr
\n" ); document.write( "==============================
\n" ); document.write( "Equation:
\n" ); document.write( "With:::: b + c = 40 km/hr
\n" ); document.write( "Against: b - c = 24 km/hr
\n" ); document.write( "--------
\n" ); document.write( "Add and solve for \"b\":
\n" ); document.write( "2b = 64
\n" ); document.write( "b = 32 km/hr (speed of the boat in still water)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"c\":
\n" ); document.write( "b + c = 40
\n" ); document.write( "32 + c = 40
\n" ); document.write( "c = 8 km/hr (speed of the current)
\n" ); document.write( "=====================================
