What time Is It?
Two watches show the same time. One of them is 1 second fast per hour. The other is 1 1/2 seconds slow per hour.
When will they show the same time again?
When will they show the correct time again?
(amendment: both watches)

Hi Kashif ...
17,280 hours (720days) is the correct amount of time required for both watches to show the same time again
However, the 2nd part of the problem was asking for how long before the both show the correct time again
2nd part - 1440 days - only cos Kashif did the hard work!
86400 hours/3600 days
Hi Karl ...
you are right .... go tickle the ivories
