To determine the distance between two numbers on a number line, you can subtract one number from the other and take the absolute value of the result.
Here, we want to find the distance between 13.48 and -3.46:
Distance = |13.48 - (-3.46)|
This simplifies to:
Distance = |13.48 + 3.46| Distance = |16.94| Distance = 16.94
Therefore, the distance between 13.48 and -3.46 on a number line is 16.94.
