One car is traveling 15 kph faster than the other. After 5 hours, the two cars are 275 km apart. Find the speed of each car \n" ); document.write( "-------------- \n" ); document.write( "1st car DATA: \n" ); document.write( "Rate = x kph ; Time = 5 hrs. ; Distance = rt = 5x km \n" ); document.write( "------------------- \n" ); document.write( "2nd car DATA: \n" ); document.write( "Rate = x+15 kph ; time = 5 hrs. ; Distance = rt = 5(x+15) km \n" ); document.write( "---------------------- \n" ); document.write( "EQUATION: \n" ); document.write( "distance + distance = 275 km \n" ); document.write( "5x + 5x+75 = 275 \n" ); document.write( "10x = 200 \n" ); document.write( "x = 20 kph (speed of 1st car) \n" ); document.write( "x+15 = 35 kph (speed of the 2nd car) \n" ); document.write( "======================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
