Let us say that the amount of speed is the same for the rest then the solution would be:\r
\n" ); document.write( "\n" ); document.write( "6x = 420
\n" ); document.write( "x = 420 / 6
\n" ); document.write( "x = 70\r
\n" ); document.write( "\n" ); document.write( "Therefore, x = 70 is considered as 1x = 70.
\n" ); document.write( "So the time required it takes to drive a 70 kilometer is just 1 hour, since 1, the coefficient of x, is the amount of hours required to drive a 70 kilometer area.\r
\n" ); document.write( "\n" ); document.write( "More so, we could apply ratio.\r
\n" ); document.write( "\n" ); document.write( "6:420::x:70\r
\n" ); document.write( "\n" ); document.write( "The formula would be 420(x)=6(70)
\n" ); document.write( "This would result in 420x = 420
\n" ); document.write( "then x = 420 / 420
\n" ); document.write( "Thus producing an x (time expressed in unit hours) equal to 1.
\n" ); document.write( "
\n" );
