Units of Time
Ancient people used lunar eclipses, the position of sun, and other seasonal events to determine the time. People used these stones to know the time of the day. In 46 BC Julius Caesar decided that the calendar year should have 365 days, but every fourth year that should have an extra day, which would be called as a "leap year". He adapted this basis because if that particular year was divisible by four then it was to be a leap year. The year can not to be a leap year unless it was divisible by 100 and 400. Conversion of Units of Time
Now let us see the example by applying the above concept to understand this topic better. Example 1: Convert 385 seconds into minutes Solution : To solve this problem let us use the conversion 1 minute = 60 seconds. Now we have to split this 385 as 360 + 25. There is 6 minutes in 360 seconds and we have to leave 25 seconds as it is. Example 2: Convert 245 seconds into minutes Solution : To solve this problem let us use the conversion 1 minute = 60 seconds. Now we have to split this 245 as 240 + 5. There is 4 minutes in 240 seconds and we have to leave 25 seconds as it is.
