A boat travels 15 miles upstream and returns.
\n" ); document.write( " If the boat travels 14 mph in still water, find the speed of the current if the total trip takes 2 hours and 20 minutes.
\n" ); document.write( ":
\n" ); document.write( "Let c = the speed of the current
\n" ); document.write( "then
\n" ); document.write( "(14+c) = effective speed downstream
\n" ); document.write( "and
\n" ); document.write( "(14-c) = effective speed upstream
\n" ); document.write( ":
\n" ); document.write( "Change 2 hrs 20 min to \"7%2F3\" hrs
\n" ); document.write( ":
\n" ); document.write( "Write a time equation: time = dist/speed
\n" ); document.write( ":
\n" ); document.write( "Upstream time + downstream time = 2 hrs 20 min
\n" ); document.write( "\"15%2F%2814-c%29\" = \"15%2F%2814%2Bc%29\" = \"7%2F3\"\r
