I flew from Pheonix to Tucson, a distance of 120 miles, at a constant speed of 120 mph,
\n" ); document.write( " I then returned at a constant speed of 60 mph.
\n" ); document.write( "what is my average speed, trip distance, displacement, and average velocity?
\n" ); document.write( ":
\n" ); document.write( "Let s = average speed
\n" ); document.write( " $\"120%2F120\"$ + $\"120%2F60\"$ = $\"240%2Fs\"$
\n" ); document.write( "3 = $\"240%2Fs\"$
\n" ); document.write( "3s = 240
\n" ); document.write( "s = 80 mph average speed, for 240 miles
\n" ); document.write( ":
\n" ); document.write( "You returned to your starting points so displacement = 0
\n" ); document.write( "Therefore the average velocity is 0 also
\n" ); document.write( ":
