Every 1 hr:
Mr Lee travel 1/6 of the journey WHILE
Mdm Ong travel 1/4 of the journey.
Therefore, making the same denominator:
Mr Lee - 1/6 = 2/12 of the journey
Mdm Ong - 1/4 = 3/12 of the journey
Both of them are traveling in opposite directions,
Therefore,
Every 1 hour, both of them would have covered 5/12 of the journey.
Every 1 minute, both of them would have covered 5/12 divide 60 = 1/144 of the journey.
Whole distance is 12/12, so total distance divide by 1/144 = 144 minutes
144 minutes = 2 hours 24 minutes
9a.m. + 2 hours 24 minutes = 11.24am
Hope this helps!
