Let time it would take Cary to get to “meeting point” be T
\n" ); document.write( "Then time it would take Kristie to get to “meeting point” is: T – 40
\n" ); document.write( "Distance covered by Cary when they meet: 10T
\n" ); document.write( "Distance covered by Kristie when they meet: 12(T – 40), or 12T – 480
\n" ); document.write( "When they meet, they would cover the same distance
\n" ); document.write( "Therefore, we get: 10T = 12T – 480
\n" ); document.write( "10T – 12T = - 480
\n" ); document.write( "– 2T = - 480
\n" ); document.write( "T, or time Cary would take to get to “meeting point” = \"%28-+480%29%2F%28-+2%29\", or \"highlight_green%28system%28240_secs_or%2C4_mins%29%29\" \n" ); document.write( "
