Dumi travels 62 miles each day from his house to school.
\n" ); document.write( "he walks to the bus stop at 4 miles per hour
\n" ); document.write( "He rides the rest of the way by bus which averages 40 miles per hour.
\n" ); document.write( " The entire trip takes 2 hours.
\n" ); document.write( "How much time does he spend walking and how much time does he spend on the bus
\n" ); document.write( ":
\n" ); document.write( "Let b = time spent on the bus
\n" ); document.write( "\"Entire trip takes 2 hrs,\" therefore:
\n" ); document.write( "(2-b) = time spent walking
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation, dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "Bus dist + walk dist = 62 mi
\n" ); document.write( "40b + 4(2-b) = 62
\n" ); document.write( ":
\n" ); document.write( "Find b, (time spent on the bus) then time walking
\n" ); document.write( "
\n" );
