Everyone knows that from planet Earth, the moon and sun appear to be about the same size, even though we know they're not the same size (from our vantage point they're the same size) hence we can get things like eclipses. The moon can go between us and the sun and block out the sun and if they didn't appear to be the same size we wouldn't have an eclipse. Now, knowing this, you can take the tip of your finger and at arms length you close one eye and you can block out the sun with the tip of your index finger. However, you go out at night and you hold that same finger up and close one eye and you can't block out the moon. How come?

WARNING: The answer is in here so don't read it if you want to figure it out on your own. ( Click to show/hide ) Because if they arrived home 20 mintues earlier than usual, he saved by walking 10 minutes of her travel time to the station and 10 minutes of her travel time from the station. Therefore, he was walking for 50 minutes when she picked him up. You have to put all of the pieces together. He left an hour earlier but she left at the same time and saves 20 minutes off the total trip. It's as if he moved the station 10 minutes closer. (10 + 50 = 60, 10 + 10 = 20) _________________________________________________ Everyone knows that from planet Earth, the moon and sun appear to be about the same size, even though we know they're not the same size (from our vantage point they're the same size) hence we can get things like eclipses.
