Why are there 24 60-min hours in a day instead of 10 100-min hours?

Because our system of timekeeping goes back to the solar days used in the Babylonian Empire, which used a base-12 (duodecimal) system of counting. This system was, in turn, based on the solar year which, with its 365.25 days, was most easily predictable with a counting system based on multiples of 12, which the Babylonians eventually evolved.
The zero, which is necessary for a 10-based system (decimal) was not invented in mathematics until about 1000 years later. It would not work for the calendar, because of the number of days in the year, but a timekeeping system of days with 10 hours, 100 minutes and 100 seconds would work fine. Each second would be about 15% shorter than our current second, but figuring out things like how many minutes in 143.6 days would be a lot easier. This has been suggested, but like the current metric system would take many years and cost billions of dollars to deploy worldwide.

How many days is 3500 minutes?
Use unit analysis to solve this problem. In one hour there are 60 minutes and in one day there are 24 hours. That is, hr/60min and day/24hr (The division can be pronounced "per", as in "60 minutes per hour" or "one hour per 60 minutes") Using these two terms, divide out the minutes and multiply in the days: 3500min * hr/60min * day/24hr The "min" units in the numerator of 35000 cancels out with the 60 min in the denominator of hr/60min. Same with the "hr". What you are left with is 3500 * 1/60 * 1day/24 Multiplying this out is approximately 2.43 with the unit of "days" left in the numerator.

Why are there 24 hour days instead of 36?
The earth takes 24 hours to complete one complete rotation about its axis. That is why there are 24 hours in a day instead of 36 or any other number of hours. If you go to some other planet, then this duration will vary.
How many minuets are in 7 days?
60 minutes in 1 hour 24 hours in 1 day The question is asking for 7 days so: 60 minutes times 24 hours in one day gives up number of minutes in a day. 60 * 24 = 1440 minutes in one day. 1440 minutes times 7 days is 10,080 minutes. So the full equation is: 60min * 24hours *7days = 10,080 60*24*7 = 10,080 minutes
