Question

When it is 11:00 a.m. in Riyadh, it is 4:00 p.m. in Manila. If your flight from Riyadh to Manila lasts 11 hours and 40 minutes, and you land at 2:00 a.m. on Monday (Manila time), what time was it in Riyadh when you left?
a.
4:20 a.m. Sunday
b.
9:20 a.m. Sunday
c.
2:20 p.m. Sunday
d.
11:20 p.m. Sunday

Answer 1

Flight arrival in Manila: Mon 2:00 a.m.
Subtract flight time 11:40 → departure in Manila = Sun 2:20 p.m.
Convert Manila → Riyadh (Manila = Riyadh +5h) → Riyadh = Manila −5h = Sun 9:20 a.m.

Answer: b. 9:20 a.m. Sunday
