each hour, there is a additional gap of 5 mins between them. so, it will need 12 hours (12x5 = 60mins) to create a gap 60mins. hence, they should be looking at the same time at 4:36am (for Veron, 04:36+12:00+00:24 = 5pm; for Wayne, 04:36+12:00-00:36 = 4pm). So, the correct time in the afternoon when they look at their watch is 04:36 + 12:00 = 16:36 = 4:36pm

Any amount from fractions or decimals to convert into %, just need to multiply 100%. :)

1 whole is 100%, 3 whole is 300%, 0.1 is 10%, 0.4 is 40%, therefore 3.4 means 340% hope this explanation is much more simpler to digest or absorb by parents
