1. Who first started tracking time as we know it - 60 sec=1 min,60 min=1 hour,24 hours=1 day,365 days=1 year?

2. What is the mathematics/basics behind this? Why didn't the people who started tracking time come up with something like this - 40 sec = 1 min, 50 mins = 1 hour, 30 hours = 1 day, 365 days = 1 year?

3. I can understand how 365 days came, but why was 1 day made to be 24 hours only and not say 30 hours (which will result in less minutes in an hour). There should be some reason behind this.
