How many minutes are in 45 kilometers?
None, since there can be no conversion from kilometers to minutes.
A kilometer is a measure of length in 1-dimensional space while a minute is a measure of time. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
16,666 minutes and 40 seconds.
Neither. The correct way to identify 12:00 is to say 12:00 noon or 12:00 midnight.
am stands for ante meridiem which means before noon and pm stands for post meridiem which means after noon. Since noon itself is neither before noon or after it, the use of am and pm is not appropriate. The same argument can be applied to midnight.
How many hours is 1130am to 7pm?
11.30 am to mid day (12.00) is 1/2 an hour
Mid day (12.00) to 7pm (19.00) is 7 hours
Therefore there are 7 and a half hours between the two.
No one invented time. It is one of the fundamental properties and dimensions of the universe we inhabit.
