You jog at a speed of 6 miles per hour for 20 minutes, and you walk at a speed of 4 miles per hour for t minutes. If your combined jogging and walking distance is 3 miles, for how long did you walk?
\n" ); document.write( "---------------
\n" ); document.write( "Jogging DATA:
\n" ); document.write( "rate = 6 mph ; time = 1/3 hr ; distance = (1/3)6 = 2 miles
\n" ); document.write( "--------------
\n" ); document.write( "Walking DATA:
\n" ); document.write( "rate = 4 mph ; time = t/60 hrs ; distance = 4(t/60) = t/15 miles
\n" ); document.write( "--------------
\n" ); document.write( "Equation:
\n" ); document.write( "dist + dist = 3 miles
\n" ); document.write( "2 miles + t/15 = 3 miles
\n" ); document.write( "t/15 = 1
\n" ); document.write( "t = 15 (# of minutes you walked)
\n" ); document.write( "=====================
