You can put this solution on YOUR website!
Create your D=RT box chart and fill in appropriately with the following data derived from your problem:
\n" ); document.write( "Car A
\n" ); document.write( "Rate: x
\n" ); document.write( "Time: 2
\n" ); document.write( "Car B
\n" ); document.write( "Rate: x+4
\n" ); document.write( "Time: 2\r
\n" ); document.write( "\n" ); document.write( "Always remember, when a problem provides you with a total distance, whether it be distance between two objects or total distance they are to travel...a total is a total. You will take the sum of the two objects R*T and set them equal to the total distance. See below:
\n" ); document.write( "2x + 2(x+4) = 192
\n" ); document.write( "Distribute
\n" ); document.write( "2x + 2x+8 = 192
\n" ); document.write( "Simplify
\n" ); document.write( "4x+8=192
\n" ); document.write( "Subtract 8 from both sides to get the x term alone
\n" ); document.write( "4x=184
\n" ); document.write( "Divide both sides by 4 to get x alone
\n" ); document.write( "x=46\r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "Take your D=RT formula and plug it into the equation created
\n" ); document.write( "2(46) + 2(46+4) = 192
\n" ); document.write( "92+100=192
\n" ); document.write( "192=192 CHECK CORRECT!!!
\n" ); document.write( "Don't forget the units (hours) when providing your solution as well as double checking what the problem asked you for. In this case it asked for the slower car: 46mph
\n" ); document.write( ":) \n" ); document.write( "
