Car A leaves Toronto for Montreal, 500km away, at an average speed of 80km/h. Car B leaves Montreal for Toronto on the same highway 2h later at 100 km/h. How far are they from Toronto when they pass?
\n" ); document.write( "---------
\n" ); document.write( "Car A DATA:
\n" ); document.write( "Rate = 80 kph ; Distance = x km ; Time = d/r = x/80 hrs
\n" ); document.write( "-------------
\n" ); document.write( "Car B DATA:
\n" ); document.write( "Rate = 100 kph ; Distance = (500-x) km ; time = d/r = (500-x)/100 hrs
\n" ); document.write( "--------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "Car A time - Car B time = 2 hrs
\n" ); document.write( "x/80 - (500-x)/100 = 2
\n" ); document.write( "Multiply thru by 800 to get:
\n" ); document.write( "10x - 8(500-x) = 1600
\n" ); document.write( "10x - 4000 + 8x = 1600
\n" ); document.write( "18x = 5600
\n" ); document.write( "x = 311.1111 km (Distance from Toronto when they pass)
\n" ); document.write( "==============
