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.
