40% of an hour also equals: 1440 seconds

Skills needed: Time Units Conversion

Step-by-step explanation:

1) First, we need to understand how to convert between hours, minutes, and seconds.

There are 60 minutes in 1 hour ==> 1 hour = 60 minutes

There are 60 seconds in 1 minute ==> 1 minute = 60 seconds

- This means that there are 3600 seconds in 1 hour ([tex]60*60=3600[/tex])

- This also means that there are 60 minutes in 1 hour

2) We are trying to find how many minutes (or seconds) 40% of an hour is.

---> When converted to decimal, [tex]40\%=\frac{40}{100}=0.4[/tex]

40% of an hour = 0.4 hours

Since there are 60 minutes in an hour, there are [tex]60*0.4[/tex] minutes in 0.4 hours. [tex]60*0.4=24[/tex] so, 24 minutes in 0.4 hours.

Since there are 3600 seconds in an hour, there are [tex]3600*0.4[/tex] seconds in 0.4 hours. [tex]3600*0.4=1440[/tex] so, 1440 seconds in 0.4 hours.

Answer:

24 minutes

1440 seconds

Step-by-step explanation:

40% = 40/100 = 0,4

1 hour = 60 minutes

60*0.4 = 24 minutes 00 secs

1 minute = 60 secs

24*60 = 1440 secs
