Suppose the fox has a speed of 8 metres per second. Draw a double number line and write the numbers on it to compare the distance in metres that the fox runs and the time in seconds that it takes to run؟

Time (seconds)
Okay, here's the double number line comparing the fox's distance (in meters) and time (in seconds), along with an explanation:
**Double Number Line**
```
Time (seconds): 0 1 2 3 4 5 6 7 8 9 10
|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|
Distance (metres): 0 8 16 24 32 40 48 56 64 72 80
```
**Explanation**
* **Top Line (Time):** Represents the time in seconds. We start at 0 and increment by 1 second for each mark.
* **Bottom Line (Distance):** Represents the distance the fox covers in metres. Since the fox runs 8 metres per second, we start at 0 and increment by 8 metres for each second that passes.
**How to Use the Number Line**
* **Find Distance for a Given Time:** If you want to know how far the fox runs in, say, 3 seconds, find '3' on the top line. Look directly below it on the bottom line, and you'll see '24'. So, the fox runs 24 metres in 3 seconds.
* **Find Time for a Given Distance:** If you want to know how long it takes the fox to run 40 metres, find '40' on the bottom line. Look directly above it on the top line, and you'll see '5'. So, it takes the fox 5 seconds to run 40 metres.
**Key Point**
The double number line visually represents the proportional relationship between time and distance when the speed is constant. For every 1 second increase in time, the distance increases by 8 metres.
