Two cars traveled in opposite directions from the same starting point. The rate of one car was 10km /h faster than the rate of the other car. After 4 hours the cars were 46okm apart. Find each car's rate.
\n" ); document.write( "----------------------
\n" ); document.write( "1st car DATA:
\n" ); document.write( "Rate = x kph ; Time = 4 hrs ; distance =rt =4x km
\n" ); document.write( "---------------
\n" ); document.write( "2nd car DATA:
\n" ); document.write( "Rate = x+10 kph ; Time = 4 hrs. ; distance = rt = 4(x+10)= 4x+40 km
\n" ); document.write( "-----------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "distance + distance = 460 km
\n" ); document.write( "4x + 4x+40 = 460
\n" ); document.write( "8x = 420
\n" ); document.write( "x = 52.5 kph (speed of the 1st car)
\n" ); document.write( "x+10 = 62.5 kph ( speed of the 2nd car)
