You can put this solution on YOUR website!
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.
\n" ); document.write( " If your combined jogging and walking distance is 3 miles, for how long did you walk?
\n" ); document.write( ":
\n" ); document.write( "We are dealing with mph, so we have to put the min over 60
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation; dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "Dist at 6mph + dist at 4mph = 3 miles
\n" ); document.write( "6* $\"20%2F60\"$ + 4* $\"t%2F60\"$ = 3
\n" ); document.write( "Cancel
\n" ); document.write( " $\"20%2F10\"$ + $\"t%2F15\"$ = 3
\n" ); document.write( "mult by 30 to clear the denominators, results
\n" ); document.write( "3(20) + 2t = 30(3)
\n" ); document.write( "60 + 2t = 90
\n" ); document.write( "2t = 90 - 60
\n" ); document.write( "2t = 30
\n" ); document.write( "t = 15 min at 4 mph \n" ); document.write( "

\n" );
