How many minutes are there in 718 hours?
There are 43,080 minutes in 718 hours.
Here is the math:
There are 60 minutes in 1 hour, therefore 60 x 718 = 43, 080 minutes
If a job ended at 817 am and lasted 9 hours 50 minutes What time did it start?
Adding 9 hours 50 minutes to 8:17am gives 6:07pm.
There can be no equivalence.
A metre (m) is a measure of length or distance in 1-dimensional space while a minute is a measure of time or angular displacement. In either case, 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.
Nobody contributed a millisecond. Around 300 BC, the Babylonians, who worked in base 60 rather than base 10, divided the day into 60. Each unit was divided into 60, and again into 60 and so on. Conceptually, this gave them an accuracy of around 2 microseconds. "Conceptually", because they had no instruments able to measure time with anything like that precision - an hour was probably the best that they could reliably measure.
In the year 1000, al-Biruni, a Persian scholar was the first to use the term second. He divided the day into hours, 1/60 of each were minutes, 1/60 of each were seconds, 1/60 of each were thirds, 1/60 of each were fourths, The last of these was 1/3600 seconds or 0.277... recurring milliseconds.
The introduction of the decimal system brought in the prefices for thousandths (milli-) and millionths (micro-) etc, and the sequence of 60ths were abandoned.
How many seconds are there in one half hour?
A half hour is 30 min so there is two half hours in an hour
60 seconds in a minute 60 minutes in an hour and 2 seconds in this answer, gg
How many milliseconds in 2 minutes?
There are 1,000 milliseconds in a second
There are 60 seconds in a minute
2 minutes * 60 seconds = 120 seconds
120 seconds * 1,000 milliseconds = 120,000 milliseconds
