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. Sundayb.9:20 a.m. Sundayc.2:20 p.m. Sundayd.11:20 p.m. Sunday

Manila is 5 hours ahead of Riyadh, since 4:00 p.m. in Manila corresponds to 11:00 a.m. in Riyadh. Subtract the 11-hour-40-minute flight from the Monday 2:00 a.m. Manila arrival to get Sunday 2:20 p.m. in Manila. That is Sunday 9:20 a.m. in Riyadh, so the correct choice is 9:20 a.m. Sunday.
