Typical Graph
This is an example of a
typical graph we are
all familiar with.
The graph is made up
of different “points”
with lines that
connect
the points.
Y axis
Each point has two

values:
The “X” value that
runs along the
horizontal “X”
axis
The “Y” value that
runs along the
vertical “Y” axis

True or False:
If EVERY part of the statement is TRUE, write T.
If ANY part of the statement is FALSE, write F.
1. The earth makes one complete rotation every 24 hours.
2. For every 15° of longitude, there is a difference of one hour in time.
3. Time zones always have straight boundaries.
4. It is 12 noon everywhere on the earth at the same time.
5. The letters a.m. stand for the 12 hours before 12 noon.
6. Post meridiem means the 12 hours after 12 noon.
7. The line of longitude at 180° is called the Prime Meridian.
8. When you travel across the International Date Line you stay in the same day.
9. When you cross the Prime Meridian, you stay in the same day.
10. It takes one hour for the earth to rotate 15°.

Assume that flying from New York to London requires 6 hours. When would a flight
leaving New York on a Wednesday at 6:00 p.m. arrive in London?
You are flying from Los Angeles to Moscow. You leave Los Angeles at 10:00 a.m. on
Saturday and you arrive in Moscow on Sunday at 9:00 a.m. How many hours did you
actually spend flying?
You are planning a flight from Bombay, India, to Washington, D.C., that must connect
through several cities. You will leave Bombay on August 2, at 8:00 A.M., and will
continue directly through Beijing and Los Angeles to Washington, D.C. What time is it

in Washington, D.C.?

North America is in the Northern Hemisphere because it is

Fractions of a Degree
 1 degree = 60 minutes or 1 minute is 1/60th of a degree
 Use minutes if location is not directly on the latitude/longitude line
 Written ----- Degree/minute = XX° xx’ compass direction
30’ is half-way
between
degrees
LONGITUDE AND TIME
 The world rotates (spins) 360° in 24 hours.
360° / 24 hours = 15° per hour
 The world has 24 time zones, each l5° apart.
THERE IS A 1 HOUR TIME
DIFFERENCE FOR EVERY 15° OF
LONGITUDE
Greenwich, England is the logical
starting point for time zones
 The world rotates west to east (counterclockwise), time
zones to the east are ahead of the those time zones to the
west
ANOTHER CHEESY SAYING
EAST INCREASE
Time is forward to all places to the east
WEST LESS
Time is backward to all places to the west
