Let both meet t hours after 9am.
\n" ); document.write( "Distance travelled by Jessica in t hours = 4.5t
\n" ); document.write( "Distance travelled by Lauren in t hours = 3.75t
\n" ); document.write( "The difference is 4.5t-3.75t = 1 mile
\n" ); document.write( " 0.75t = 1
\n" ); document.write( " t = 1/0.75 hours
\n" ); document.write( " t = 1 1/3 hours
\n" ); document.write( " t = 1h 20m
\n" ); document.write( "
