A toy car drove along a track marked like a number line. It started at and ended at . What was its change in position? (That is, find the total directed distance traveled. A directed distance can be positive or negative.) Enter an expression that includes the two numbers in the problem. For instance, 42 + 11 and 11/42 are examples of expressions that include 11 and 42. Use parentheses if you need them. 1 2 3 4 5 6 7 8 9 10 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 start end 0

Answer:

The change in position, or total directed distance traveled, can be found by calculating the difference between the end position and the start position.

So, the expression is:

\[ \text{End position} - \text{Start position} \]

In this case, the end position is \( 10 \) and the start position is \( -10 \), so the change in position is:

\[ 10 - (-10) \]
