At night, I usually sleep between
six and nine what.
This question is is just a simple
sentence. It’s about how long somebody
sleeps. At night, I usually sleep between
six and nine what. The way this sentence has been
written, we know that this missing word is going to be a unit of measurement used to
measure time. Let’s go through some different
units of time and see which one makes most sense.
At night, I usually sleep between
six and nine seconds. We know that a second is about the
same time as it takes to clap our hands or blink or even to say a number. So nine seconds is the length of
time it might take us to count to nine. I think we sleep a little bit
longer than this at night, don’t you?
What about minutes? At night, I usually sleep between
six and nine minutes. Now, remember, one minute is the
time it takes for the minute hand on a clock to move one little notch around the
clock face. A minute is worth 60 seconds. So do you think if I counted to 60
nine times, that’s as long as you’re going to sleep for? I don’t think so. It’s still too short, isn’t it?
What about hours? Is this a better unit of
measurement? An hour is worth 60 minutes. And it’s the time it takes to go
from one o’clock time to another. So if somebody went to bed at 10
o’clock, nine hours would be 11 o’clock, 12 o’clock, one o’clock, two o’clock, three
o’clock, four o’clock, five o’clock, six o’clock, seven o’clock in the morning. This sounds about right, doesn’t
it? Going to bed at 10 o’clock at night
and getting up again at seven o’clock in the morning. The unit of measurement that makes
most sense here is hours. At night, I usually sleep between
six and nine hours.
