Something is wrong with this problem.

If Mang Lorenzo did 2 hours of a 3-hour job, he hdid 2%2F3 of the job, leaving the other 1%2F3 of the job unfinished.
If Aling Tina did that 1%2F3 of the job in 1.5 hours (1 hour and 30 minutes), it would take Aling Tina 3 times as long to do the entire mowing job.
That would be
3%2A1.5hours=4.5hours= 4 hours and 30 minutes.
That is not 2 hours and 22 minutes.
