The distance between 19 and -15 on a number line is 4?

See explanation below.

Step-by-step explanation:

No.

The distance between 19 and 15 is 4. Both numbers are positive, 4 units apart.

The distance between -19 and -15 is also 4. Both numbers are negative, 4 units apart.

When you find the distance from 19 to -15, keep in mind that one number is positive, 19, and one number is negative, -15. The two numbers are on different side of zero on the number line.

Start at -15. -15 is 15 units to the left of zero. To get to 0, you need to go 15 units right. Now you need to go from 0 to 19. That is another 19 units right. Add 15 + 19 to get 34.

The distance from 19 to -15 on a number line is not 4. It is 34.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
