Two families drive from Kingston to Niagara Falls. The Maretti family leaves first and travels at an average speed of 85 km/h. The Khan family leaves Kingston once the Maretti family has travelled 40 km, and travels at an average speed of 95 km/h. Determine how far they have travelled when the families have both gone the same distance.
\n" ); document.write( "--------------
\n" ); document.write( "Maretti family DATA:
\n" ); document.write( "rate = 85 km/h ; distance = x -40 km ; time=(x-40)/85 hr.
\n" ); document.write( "------
\n" ); document.write( "Khan family DATA:
\n" ); document.write( "rate = 95 km/h ; distance = x km ; time=x/95
\n" ); document.write( "----------
\n" ); document.write( "EQUATION:
\n" ); document.write( "Time = time
\n" ); document.write( "(x-40)/85 = x/95
\n" ); document.write( "95x - 3800 = 85x
\n" ); document.write( "10x=3800
\n" ); document.write( "x=380 km
\n" ); document.write( "They have both gone 380 km.\r
