Mathematics for IGCSE & O level - Time (Section 2 - No. 7)
An aircraft leaves Dubai at 08:55 local time and arrives in Sydney at 22:10 local time. The flight time is 13 hours 40 minutes. How many hours ahead of Dubai time is Sydney time?
8 hours
9 hours
10 hours
7 hours
Explanation
Arrival time in Dubai: 22:10 - 13:40 = 08:30. Sydney time is 08:30 + 13:40 = 22:10 (Dubai time) Dubai time + hours = Sydney time. So 08:55 + 13:40 = 22:35 So, Sydney Time is 10 hours ahead of Dubai Time.
