Question

cole was staying in a hotel with some friends. he walked 0.2 kilometers down the hallway to the gym. he then walked 0.1 kilometers in the same direction to his friends room. together, they walked 0.2 kilometers in the same direction to the pool. after swimming, they walked 0.3 kilometers in the same direction out the exit to coles car. assume the direction cole started walking is the positive direction. what was coles displacement? \boxed{} kilometers

Explanation:

Step1: List all positive displacements

All distances are in the positive direction, so we have: $0.2$, $0.1$, $0.2$, $0.3$

Step2: Sum all displacements

$\text{Total displacement} = 0.2 + 0.1 + 0.2 + 0.3$

Step3: Calculate the total

$0.2 + 0.1 + 0.2 + 0.3 = 0.8$

Answer:

0.8 kilometers
