Sherry maneuvered her way through the first 60 miles in 4 hours. Then she doubled her speed for the last part of the trip. If the total trip was 300 miles,how many hours did it take Sherry to complete the last part?\r
\n" ); document.write( "\n" ); document.write( "First she went at 60 mph for 60 miles\r
\n" ); document.write( "\n" ); document.write( "Then she went at 120 mph for 240 miles\r
\n" ); document.write( "\n" ); document.write( "The time taken for the last part = Distance / rate\r
\n" ); document.write( "\n" ); document.write( "= 240 / 120= 2 hours
\n" ); document.write( "
