You can put this solution on YOUR website!
Given function: f(x) = 120 - 25x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Replace f(x) with 0. Then solve for x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f(x) = 120 - 25x
\n" ); document.write( "0 = 120 - 25x
\n" ); document.write( "0+25x = 120 - 25x+25x
\n" ); document.write( "25x = 120
\n" ); document.write( "25x/25 = 120/25
\n" ); document.write( "x = 4.8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The 120 refers to how far the ship is from the destination at the beginning of the trip. Then 4.8 hours later, the distance from the destination is 0 miles.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The ship traveled 120 miles in 4.8 hours.
\n" ); document.write( "
\n" );
