Sharon drove 295 miles 5 1/2 hours.
\n" ); document.write( " she drove at an average rite of 45 mph for the first 3 hours.
\n" ); document.write( " what was her average rate for the reminder of the trip?
\n" ); document.write( ":
\n" ); document.write( "Let r = the rate for the 2nd part of the trip
\n" ); document.write( "5.5 - 3 = 2.5 hrs for the 2nd part
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation, dist = speed * time
\n" ); document.write( "3(45) + 2.5r = 295
\n" ); document.write( "135 + 2.5r = 290
\n" ); document.write( "2.5r = 295 - 135
\n" ); document.write( "2.5r = 160
\n" ); document.write( "r = 160/2.5
\n" ); document.write( "r = 64 mph on the 2nd part of the trip
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check the solution by finding the distances
\n" ); document.write( "3(45) + 2.5(64) =
\n" ); document.write( "135 + 160 = 295
\n" ); document.write( " \n" ); document.write( "
\n" );
