During the first part of a trip, a canoeist travels 94 miles at a certain speed.
\n" ); document.write( "dist = 94 miles ; rate = x mph ; time = 94/x hrs
\n" ); document.write( "------------------------------------\r
\n" ); document.write( "\n" ); document.write( "The canoeist travels 15 miles on the second part of the trip at a speed 5 mph slower.
\n" ); document.write( "dist = 15 miles ; rate = x-5 ; time = 15/(x-4) hrs
\n" ); document.write( "---------------------------------------\r
\n" ); document.write( "\n" ); document.write( "The total time for the trip is 4 hours.
\n" ); document.write( "time + time = 4 hrs
\n" ); document.write( "94/x + 15/(x-5) = 4
\n" ); document.write( "---
\n" ); document.write( "94(x-4) + 15x = 4x(x-5)
\n" ); document.write( "94x-376 + 15x = 4x^2-20x
\n" ); document.write( "109x - 376 = 4x^2-20x
\n" ); document.write( "---
\n" ); document.write( "4x^2-129x+376 = 0
\n" ); document.write( "x = 29 mph (1st leg speed)
\n" ); document.write( "x-5 = 24 mph (2nd leg speed
\n" ); document.write( "=========
