You can think of one helicopter as standing
\n" ); document.write( "still and the other moving at the sum of their speeds
\n" ); document.write( "Let $\"+t+\"$ = the time in hours for them to be
\n" ); document.write( " $\"+2025+\"$ km apart
\n" ); document.write( " $\"+2025+=+%28+350+%2B+325+%29%2At+\"$
\n" ); document.write( " $\"+t+=+2025+%2F+675+\"$
\n" ); document.write( " $\"+t+=3+\"$
\n" ); document.write( "It will take them 3 hrs
\n" ); document.write( " \n" ); document.write( "
