What is the time problem?
In theoretical physics, the problem of time is
a conceptual conflict between general relativity and quantum mechanics
in that quantum mechanics regards the flow of time as universal and absolute, whereas general relativity regards the flow of time as malleable and relative.
How do you solve time Questions?
- Work Done = Time Taken × Rate of Work.
- Rate of Work = 1 / Time Taken.
- Time Taken = 1 / Rate of Work.
- If a piece of work is done in x number of days, then the work done in one day = 1/x.
- Total Wok Done = Number of Days × Efficiency.
- Efficiency and Time are inversely proportional to each other.

- Take your number of minutes and divide by 60. In this example your partial hour is 15 minutes: …
- Add your whole hours back in to get 41.25 hours. So 41 hours, 15 minutes equals 41.25 hours.
- Multiply your rate of pay by decimal hours to get your total pay before taxes.
How do you solve rate time distance problems?
The formula for distance problems is:
distance = rate × time or d = r × t
. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
How do you calculate work time and efficiency?
efficiency = (10 + 20)% = 30%
. This means in one day A and B together can do 30% of the work. Therefore, Number of days A and B together take to do 100% of work = (100/3) days = 3.33 days. Example 3: A can do a certain work in 12 days.
