During a multi-day camping trip, Jacque rowed 17 hours downstream.
\n" ); document.write( " It took 26.5 hours rowing upstream to travel the same distance.
\n" ); document.write( "If the speed of the current is 6.8 kilometers per hour less than his
\n" ); document.write( " rowing speed in still water, find his rowing speed and the speed of the current.
\n" ); document.write( ":
\n" ); document.write( "Let s = his rowing speed
\n" ); document.write( "then
\n" ); document.write( "(s-6.8) = speed of the current
\n" ); document.write( ":
\n" ); document.write( "write a distance equation; dist = time * speed
\n" ); document.write( ":
\n" ); document.write( "downstream dist = upstream dist
\n" ); document.write( "17(s + (s-6.8)) = 26.5(s - (s-6.8))
\n" ); document.write( ":
\n" ); document.write( "17(s + s - 6.8) = 26.5(s - s + 6.8)
\n" ); document.write( ":
\n" ); document.write( "17(2s - 6.8) = 26.5(6.8)
\n" ); document.write( ":
\n" ); document.write( "34s - 115.6 = 180.2
\n" ); document.write( ":
\n" ); document.write( "34s = 180.2 + 115.6
\n" ); document.write( ":
\n" ); document.write( "34s = 295.8
\n" ); document.write( "s = \"295.8%2F34\"
\n" ); document.write( "s = 8.7 km/hr; rowing speed
\n" ); document.write( "then
\n" ); document.write( "8.7 - 6.8 = 1.9 km/hr; current
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution by finding the dist:
\n" ); document.write( "17(8.7+1.9) = 180.2
\n" ); document.write( "26.5(8.7-1.9) = 180.2; confirms our solutions
