Question

40% of an hour in minutes and secs

Answer 1

24 minutes

1440 seconds

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

Answer 2

40% of an hour equals: 24 minutes

40% of an hour also equals: 1440 seconds

Skills needed: Time Units Conversion

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 (
`60*60=3600`)

- 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,
`40\%=(40)/(100)=0.4`

40% of an hour = 0.4 hours

Since there are 60 minutes in an hour, there are
`60*0.4` minutes in 0.4 hours.
`60*0.4=24` so, 24 minutes in 0.4 hours.

Since there are 3600 seconds in an hour, there are
`3600*0.4` seconds in 0.4 hours.
`3600*0.4=1440` so, 1440 seconds in 0.4 hours.
