How do you calculate a fraction of an hour?
The same as you calculate the fraction of anything. For example, a fifth of an hour is one part out of five equal parts of a whole hour.
How many hours is 11 30am to 3 30 pm?
The time from 11:30 AM to 3:30 PM is 4 hours. You can calculate this by counting the hours from 11:30 AM to 12:30 PM (1 hour), then from 12:30 PM to 1:30 PM (1 hour), from 1:30 PM to 2:30 PM (1 hour), and finally from 2:30 PM to 3:30 PM (1 hour). Adding these together gives a total of 4 hours.
How many minutes are in the time interval from 122 P.M. to 544 P.M.?
262
38 + 180 + 44 = 262
240 + 22 = 262
How is the use of local time inconvenient in the practical life?
Strictly speaking, local time is when the sun is at its highest in the sky. This changes by an hour for every 1600 kilometres (1000 miles) at the equator and much less than that at higher latitudes. This is equivalent to a difference of 1 minute for every 26.67 km (16.67 miles) so that , for some of our larger cities, the time between end of the city and another would differ by a minute. In the modern world, where computers and satellites interact on time cycles which are considerably shorter, this would lead to chaos.
How many minutes are there from 148 PM to 636 PM?
There are 5 hours and 48 minutes between 1:48 pm and 6:36 pm.
What is 1254 in analogue time?
It is when the big hand on a clock face is at 54 and the little hand is a tiny bit short of 1 (27 degrees instead of 30 degrees).
How long does it take for the minute hand on a clock to pass through 2.5 p radians?
1 radian = approx 9.5 minutes so 2.5 radians = 23.9 minutes. Therefore 2.5 p radians = 23.9p minutes.
