Hint: One hour is equal to sixty seconds. One day is equal to twenty-four hours. One week is equal to seven days. Calculate the number of seconds in a day. If we know the number of seconds in a day, we can easily calculate the number of seconds in a week.
Complete step by step answer:
We know, one day contains twenty-four hours and one hour is equal to sixty minutes. In turn, one minute is equal to sixty seconds. So, lets first calculate the number of seconds in a day,
Now, we knew the number of seconds per day, lets calculate for the week,
Which is,
So, the correct answer is “Option B”.
Additional Information: Second is one of the seven si base units. It means that it is used to build the foundations of many other units. Other units of time include minutes, hours, days, weeks, months and years. One second also refers to the caesium atom at rest at a temperature of zero kelvins. The ground state of a caesium atom is defined at zero magnetic field. The international standard symbol for a second is s. Intently, second was known as second minute meaning the small division of time. The first division was known as prime minute and is equivalent to the minute we know today. During the Greek time periods, meaning the synodic month, were used to specify the time precisely because they were calculated from carefully selected eclipses separated by hundreds of years.
Note: One minute is used as the basic unit of time till date. There are fractions of seconds for minute calculations but the primary unit of time is only second, there’s no other measurement unit smaller than second as of now. One second is also proposed by the royal society of London.
