How do you find the difference in time?

How do you find the difference in time?

1. Convert both times to 24 hour format, adding 12 to any pm hours. 8:55am becomes 8:55 hours (start time)
2. If the start minutes are greater than the end minutes…
3. Subtract end time minutes from start time minutes…
4. Subtract the hours…
5. Put(not add) the hours and minutes together – 6:45 (6 hours and 45 minutes)

How do you solve time Questions?

Know the important formulae and rules to solve questions based on time & work….FORMULAS

1. The basic formula for solving is: 1/r + 1/s = 1/h.
2. Let us take a case, say a person Hrithik.
3. Let us say that in 1 day Hrithik will do 1/20th of the work and 1 day Dhoni will do 1/30th of the work.

What is the formula for time and work?

Important Time and Work Formula 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.

How do you find the rate of work done?

Power is a rate at which work is done, or energy is used. It is equal to the amount of work done divided by the time it takes to do the work. The unit of power is the Watt (W), which is equal to a Joule per second (J/s).

What is the formula for calculating power?

Power = force multiplied by speed (velocity) P = F × v.

What is power write its formula?

P = W / t. The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second.

What is the SI unit of power?

watt

What is the efficiency formula?

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.

How do u calculate speed?

Google Maps can tell you your speed, it has an inbuild speedometer, which is only currently for Android users. It is on by default, but to make sure if it is on, go to settings → navigation settings, and under the driving options menu there will be a slider for it.
