You can put this solution on YOUR website!
there's two ways to solve this one
\n" ); document.write( "logic: if it took 15 days to drive 500 miles then it would take 10 times as much to drive a distance ten times further at the same speed, since 5000 is ten times more than 500, meaning 500(10)=5000
\n" ); document.write( "so all you have to do is multiply the number of days it took to drive 500 miles by ten
\n" ); document.write( "15(10)=150\r
\n" ); document.write( "\n" ); document.write( "math: i always do these ratio kind of problems this way (it would only apply if the speed is the same)\r
\n" ); document.write( "\n" ); document.write( "it took 15 days to drive 500
\n" ); document.write( "then it would take x to drive 5000\r
\n" ); document.write( "\n" ); document.write( "i write then down like this
\n" ); document.write( "15 --- 500
\n" ); document.write( "x --- 5000
\n" ); document.write( "then i multiply across
\n" ); document.write( "15(5000)=500x
\n" ); document.write( "divide both sides by 500, then you get
\n" ); document.write( "15(5000)/500=x
\n" ); document.write( "x=150
\n" ); document.write( " \n" ); document.write( "
\n" );
