Question

kwafobea is walking along a straight path on an axis in which moving from right to left is positive. what is her displacement and distance when she walks 32 m to the left and then 17 m to the right? displacement is ...... and the distance is .........respectively.
15 m, 49 m
15 m, -49 m

Explanation:

Step1: Define direction signs

Left = positive, Right = negative

Step2: Calculate displacement

$\text{Displacement} = 32\ \text{m} + (-17\ \text{m}) = 15\ \text{m}$

Step3: Calculate total distance

$\text{Distance} = |32\ \text{m}| + |17\ \text{m}| = 32\ \text{m} + 17\ \text{m} = 49\ \text{m}$

Answer:

A. 15 m, 49 m
