Accra is at greenwich meridian and whindhoek is at 17° E longitude. a) Which place between the two receives sunrise first. b) What is the difference in time between the two places

Accra iko kwenye Greenwich Meridian, ambayo ni $0^{\circ}$ longitudo. Windhoek iko $17^{\circ}E$ longitudo.

Maeneo yaliyo mashariki (East) hupata jua mapema kuliko yale yaliyo magharibi (West). Kwa kuwa $17^{\circ}E$ iko mashariki mwa $0^{\circ}$, Windhoek itapata jua kwanza.

Jibu:

a) Windhoek

b)

Tofauti ya longitudo ni:

Tunajua kuwa $1^{\circ}$ ya longitudo ni sawa na dakika 4 za muda.
Tofauti ya muda = Tofauti ya longitudo $\times$ dakika 4/digrii

Kuna dakika 60 katika saa 1.

Jibu:

b) Tofauti ya muda kati ya maeneo hayo mawili ni $\boxed{\text{1 saa na 8 dakika}}$.
