At 2 am snow started falling at a constant rate. At 10:30 am Harry began clearing his driveway at a constant rate. At 11 am when it stopped snowing the average depth of the snow on the driveway was 2 in. By 11:24 the driveway was clear. At what rate did the snow fall in in./hour.
\n" ); document.write( ":
\n" ); document.write( "Get some facts in our mind, and write them down:
\n" ); document.write( ":
\n" ); document.write( "No. hrs the snow fell: 11:00 - 2:00 = 9 hrs
\n" ); document.write( "No. hrs shoveling snow: 11:24 - 10:30 = :54 min; 54/60 = .9 hrs
\n" ); document.write( "No. hrs shoveling after the snowing stopped: 11:24 - 11:00 = :24 min = 24/60 = .4 hr
\n" ); document.write( ":
\n" ); document.write( "At 11 the snow was 2 in deep and at 11:24 it was gone, therefore
\n" ); document.write( "He shoveled at a rate of 2 in .4 hr or at a rate of 2/.4 = 5 inches/hr
\n" ); document.write( ":
\n" ); document.write( "Let x = snowfall in inches/hr:
\n" ); document.write( ":
\n" ); document.write( "Fallen snow - shoveled snow = 0
\n" ); document.write( "9x - .9(5) = 0
\n" ); document.write( "9x - 4.5 = 0
\n" ); document.write( "9x = +4.5
\n" ); document.write( "x = 4.5/9
\n" ); document.write( "x = .5 inches per hr
\n" ); document.write( ":
\n" ); document.write( "Did this make some sense to you? Any questions? \n" ); document.write( "
