Question

A person walks from x = 2 m to x = 5 m, and then immediately returns to x = 4 m. What is the total path length covered?

Options

• 2 m

• 3 m

• 4 m

• 6 m

Answer 1

4 m

Explanation:

The path length for the first segment is |5 - 2| = 3 m, and the second segment is |4 - 5| = 1m, so the total path length is 3 m + 1 m = 4 m.
