You can
put this solution on YOUR website! You're catching a plane. The plane leaves at 5:35 am. It takes 21 hours to reach your destination. What time will you arrive at your destination?
That depends on which time zone your destination is in when
you arrive. If we knew that the plane flew due east or due
west, and the speed of the plane we could figure it out, but
all we can say is that the time will be 35 minutes after
some hour. There isn't enough information.
