Time on a number line example

·Nov 10, 2024

We're told to look at the following number line, and this number line we actually have times on it, so you could even call it a timeline. We're starting at one o'clock here. Then we go to 1:15, 1:30, 1:45, then 2 o'clock. It says, "What time is shown on the number line?" So pause this video and see if you can figure that out.

Alright, so the hour I think is pretty straightforward. We are past one o'clock, but we are before two o'clock, so we know that the hour is going to be one something. It's not going to be two something because we haven't gotten to two o'clock yet.

Now, what is the number of minutes after one o'clock? Well, we have a hint here—it's going to be between 15 and 30. And where would it be? Well, one way to tell is if you look at each of these tick marks, it looks like they represent a minute. Let's just count. If we start at 1, we go to 1:01, 1:02, 1:03, 1:04, 1:05, 1:06, 1:07, 1:08, 1:09, 1:10, 1:11, 1:12, 1:13, 1:14, 1:15. Yup! It looks like each of these tick marks is a minute, so we just have to figure out how many tick marks we are past 1:15.

So, we can see that we can go from 15 to 16, 17, 18, 19, 20, 21, 22, 23, 24, 25. So, we're 25 minutes past one o'clock. Another way you could have thought about it is each of these medium tick marks represent five minutes, and you can count: one, two, three, four, five—so that's five. That's another five. So, this time right over here is going to be five plus five is ten. It's going to be 10 minutes past 1:15.

Well, 15 plus 10 is 25 again. So, the time shown on the number line is 1:25.
