Last time we learned about measuring Distance.
Another thing we can measure is called Time.
We can look at a clock to see what time it is,
and we can also use the clock to count how much time has passed.
So if you get in the car and drive to Gramma's house,
if it takes 30 minutes then that is the time measured.
Time is usually measured in seconds, and there are 60 seconds in each minute.
So if you know your math, you can take 30 times 60 = 18,000 seconds.
