Ayear has 365 days, and a day has 24 hours. if an hour has 60 minutes and a minute has 60 seconds, how many seconds are there in 1 year? 54,750 s 525,600 s 3.15 107 s 1.89 109 s

Here we need to convert year into seconds.

so lets do it step by step

first lets convert year to hours

1 year has 365 days - 365 days per year

and a day has 24 hours - 24 hours per day

therefore 1 year will have -1 year x  365 days per year x 24 hours per day

                                         = 8760 hours

next convert hours to seconds

1 hour has 60 minutes - 60 minutes per hour

and 1 minute has 60 seconds - 60 seconds per minute

since 1 year has 8760 hours

8760 hours will have - 8760 hours x 60 minutes per hour x 60 seconds per minute

                                   = 31 536 000 seconds = 3.15 x 10⁷ s

answer is 3.15 x 10⁷ s in one year
