Question

reggie went to a music festival. he walked 0.4 miles through the festival to find his friends. together, they walked 0.2 miles in the same direction to the stage to listen to their favorite band. then, they continued another 0.2 miles in the same direction to buy some shirts at the merchandise tent. finally, they walked 1.1 miles in the opposite direction back to their cars. assume the direction reggie started walking is the positive direction. what was reggies displacement? miles

Explanation:

Step1: Calculate the total distance in the positive - direction

Add up the distances walked in the positive direction: $0.4 + 0.2+0.2=0.8$ miles.

Step2: Consider the distance in the negative - direction

The distance walked in the opposite (negative) direction is 1.1 miles.

Step3: Calculate the displacement

Displacement is the net distance from the starting point. Subtract the distance in the negative direction from the distance in the positive direction: $0.8−1.1=- 0.3$ miles.

Answer:

$-0.3$
