Answer to Question 1

E

Answer to Question 2

The reflection of sound is used to determine distance. A transmitter sends out a sound pulse through the water, and a detector receives its reflection, or echo, a short time later. This time interval is carefully measured, and from it the distance to the reflecting object can be determined since the speed of sound in water is known.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
