s = d / t
\n" ); document.write( "d = s * t
\n" ); document.write( "---
\n" ); document.write( "when they meet, both cars are at the same distance (D) from the departure point
\n" ); document.write( "D = 40t
\n" ); document.write( "D = 50(t - 1)
\n" ); document.write( "D = 50t - 50
\n" ); document.write( "---
\n" ); document.write( "D = 40t = 50t - 50
\n" ); document.write( "10t = 50
\n" ); document.write( "---
\n" ); document.write( "t = 5 hours
