The airplane takes off 12 1/2 miles south of a city
\n" ); document.write( "speed =180 mph
\n" ); document.write( "duration = 45 min = 45/60 hrs = 3/4 hr
\n" ); document.write( " distance traveled during 45 min = speed * time
\n" ); document.write( " = $\"180%2A%283%2F4%29\"$
\n" ); document.write( " =45*3
\n" ); document.write( " =135 miles
\n" ); document.write( "so plane traveled 135 miles due north
\n" ); document.write( "but plane already traveled 12.5 miles south
\n" ); document.write( " effective distance traveled in north direction = 135-12.5
\n" ); document.write( " =122.5 miles
\n" ); document.write( "plane is 122.5 miles north to the city after 45 min
\n" ); document.write( " \n" ); document.write( "

\n" );
