89 miles at a certain speed. the canoist travels 12 miles on the second
\n" ); document.write( " part of the trip 5 mph slower.
\n" ); document.write( "the total time for trip was 4 hours
\n" ); document.write( "What was the speed on the first part of the trip
\n" ); document.write( ":
\n" ); document.write( "obviously, the 1st part is not 89 miles, assume it's 8 miles
\n" ); document.write( "Let s = his speed on the 1st part
\n" ); document.write( "then
\n" ); document.write( "(s-5) = his speed on the last 12 mi
\n" ); document.write( ":
\n" ); document.write( "Write a time equation: Time = dist/speed
\n" ); document.write( " $\"8%2Fs\"$ + $\"12%2F%28%28s-5%29%29\"$ = 4
\n" ); document.write( ":
\n" ); document.write( "This is the equation, if the first part is not 8 miles, replace it, solve for s \n" ); document.write( "

\n" );
