Expert Answer:

Time taken by individual to complete one round,

360/48 = 7.5 day = 180 hrs.

360/60 = 6 day = 144 hrs

360/72 = 5 day = 120 hrs.

They will after a time equal to the HCF.

180 = 22 x 5x 32

144 = 24 x 32

120 = 23 x 3 x 5

HCF = 24 x 32 x 5 =  720 hrs or 720/24 = 30 day.

They'll meet again after 30 days at the same point.
