Betty leaves her purse in a store at the mall and averages 36mi/h on her way home to Glenville, 140 miles away.
\n" ); document.write( "Betty distance: 36x miles
\n" ); document.write( "------------------------------------
\n" ); document.write( "Honest Harry discovers her purse and starts after her one hour later. If he averages 48mi/h, how long will it take him to catch Betty ?
\n" ); document.write( "Harry distance: 48(x-1) miles
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "distance = distance
\n" ); document.write( "36x = 48x-48
\n" ); document.write( "12x = 48
\n" ); document.write( "x = 4 hours (time needed for Harry to go the same distance as Betty)
\n" ); document.write( "-------
\n" ); document.write( "Will he catch her before she reaches Glenville ?
\n" ); document.write( "In 4 hours she could have gone 4*36 = 144 miles
\n" ); document.write( "------
\n" ); document.write( "He will not catch her before she reaches Glenville.
