Question 1 Report
(a) Distinguish between Meridians and Parallels.
(b) A football match is to be played on Saturday in New Zealand (150°E) between the host country and Nigeria (15°E). If the match is to be televised live, at what time should Nigerians tune in their television sets to watch the kick-off scheduled for 4.00 p.m. in New Zealand?"
Answer Details
(a) Distinction between Meridians and Parallels
| Meridians (lines of longitude) | Parallels (lines of latitude) |
|---|---|
| They run from the North Pole to the South Pole (north-south). | They run east-west, parallel to the Equator. |
| They measure distance east or west of the Prime Meridian (0 degrees). | They measure distance north or south of the Equator (0 degrees). |
| They are all of equal length (all are half great circles) and meet at the poles. | They are of unequal length, decreasing from the Equator (longest) towards the poles (a point). |
| They are used to determine local time and time zones. | They are used to determine climatic/temperature zones. |
(b) Time calculation
Given: New Zealand kick-off is 4.00 p.m. at longitude 150 E; Nigeria is at longitude 15 E.
Step 1 - difference in longitude (both places are east, so subtract):
\[150^{\circ}E - 15^{\circ}E = 135^{\circ}\]
Step 2 - convert to time (1 degree = 4 minutes):
\[135 \times 4 = 540 \text{ minutes} = 9 \text{ hours}\]
Step 3 - apply the difference. New Zealand (150 E) lies east of Nigeria (15 E), so its time is ahead. Nigeria is therefore 9 hours behind New Zealand:
\[4.00\text{ p.m.} - 9\text{ hours} = 7.00\text{ a.m.}\]
Answer: Nigerians should tune in their television sets at 7.00 a.m. (on the same Saturday) to watch the kick-off.
