a steamboat travels 14 km/h faster than a freighter. the steamboat travels 84km in the same time the freighter travels 49 km. what is the speed of each boat?
\n" ); document.write( "-----------------------
\n" ); document.write( "Freighter DATA:
\n" ); document.write( "rate = x km/h ; distance = 49 km ; time = d/r = 49/x hrs
\n" ); document.write( "--------------------------
\n" ); document.write( "Steamboat DATA:
\n" ); document.write( "rate = x+14 km/h ; distance = 84 km ; time = d/r = 84/(x+14) hrs
\n" ); document.write( "--------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "time = time
\n" ); document.write( "49/x = 84/(x+14)
\n" ); document.write( "84x = 49(x+14)
\n" ); document.write( "84x = 49x + 49*14
\n" ); document.write( "35x = 48*14
\n" ); document.write( "x = 19.2 km/h (speed of the freighter)
\n" ); document.write( "x+14 = 33.2 km/h (speed of the steamboat)
