Hours, minutes and seconds
Lesson

Seconds, minutes, and hours all are units of time. The smallest unit of the three is seconds. A second is approximately the time between 2 heartbeats. it takes $60$60 seconds to make up $1$1 minute, and it takes $60$60 minutes to make up an hour.

Knowing this relationship helps us to convert between seconds, minutes, and hours.

We can use multiplication and division to change between them.

If we want to know how many seconds are in $5$5 minutes of time, we can multiply that by $60$60 seconds because there are $60$60 seconds for each minute. $5\times60=300$5×60=300, so there are $300$300 seconds in $5$5 minutes.

 

Watch this video to see a couple examples.


Remember!
$1$1 Week $=$= $7$7 Days
$1$1 Day $=$= $24$24 Hours
$1$1 Hour $=$= $60$60 Minutes
$1$1 Minute $=$= $60$60 Seconds
