JAMB Geography 2018 Paper

Question : 60

Total: 70

Solution:

Concept:

The Earth rotates

15^\circ

per hour, so places west of Greenwich record earlier local time.

Explanation:

Longitude difference between Greenwich (

0^\circ

) and the place is

75^\circ

west.

Time difference =

\frac{75^\circ}{15^\circ} = 5

hours.

Since the place is west of Greenwich, local time is

5

hours behind GMT.

So, local time =

11:00\text{ am} - 5\text{ hours} = 6:00\text{ am}

Answer:

6:00\text{ am}

(Option D) is correct.
