The coordinates of Cairo are \( (30^{\circ}\text{N}, 31^{\circ}\text{E}) \).

What are the coordinates of Athens if it is 23° west of Cairo and on the same line of longitude?

  1. \( (30^{\circ}\text{N}, 54^{\circ}\text{E}) \)
  2. \( (7^{\circ}\text{N}, 31^{\circ}\text{E}) \)
  3. \( (53^{\circ}\text{N}, 31^{\circ}\text{E}) \)
  4. \( (30^{\circ}\text{N}, 8^{\circ}\text{E}) \)

\(\text{Athens is 23° west of Cairo.}\)

\(\text{Latitude of Athens}=30^{\circ}\text{N}\)

\(\text{Longitude of Athens}=31^{\circ}-23^{\circ}=8^{\circ}\text{E}\)

\(\therefore\ \text{Coordinates of Athens are:}\ (30^{\circ}\text{N}, 8^{\circ}\text{E})\)

\(\Rightarrow D\)
