(150*3)^2+(200*3)^2=d^2
\n" ); document.write( "450^2+600^2=d^2
\n" ); document.write( "202,500+360,000=d^2
\n" ); document.write( "562,500=d^2
\n" ); document.write( "d=sqrt562,500
\n" ); document.write( "d=750 miles. ans. for the distance between these 2 planes @ 3:00 PM.
\n" ); document.write( "
