Question

40% of an hour in minutes and secs

Answer 1

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

Answer 2

Answer:

40% of an hour equals: 24 minutes

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 ($60*60=3600$)

- 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, $40\%=\frac{40}{100}=0.4$

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.
