JAMB Geography 2019 Paper

Question : 25

Total: 78

Solution:

Concept:

GMT + 1 hr means local time is one hour ahead of Greenwich, so the longitude must be east of the Prime Meridian.

Explanation:

The Earth rotates

360^\circ

in 24 hours, so each hour corresponds to

\frac{360^\circ}{24} = 15^\circ

of longitude.

Since the country is GMT + 1 hr, it is one hour ahead, meaning it is east of Greenwich.

Therefore, the adopted longitude is

15^\circ\,\mathrm{E}

Answer:

15^\circ\,\mathrm{E}
