Ratio of loss of tinme of Jackies warch to the gain of time of Adam's watch is 2 : 1
Let the number of hour ellapsed at the time they are twelve minutes apart be x, then
2x + x = 12
⇒ 3x = 12
⇒ x = 12 / 3 = 4
Thus, after 4 hours Jackie's watch has lost 8 minutes and Adam's watch has gained 4 minutes.
Therefore, the real time at the time they arrive at the airport is 10:00 am.
