Question

shivani went for a bike ride across the golden gate bridge. she biked 1.7 miles, then turned around and biked 0.4 miles back toward her original location to capture a photo of the view. assume the direction shivani started biking is the positive direction. what distance did shivani bike? * what was shivanis displacement?

Explanation:

Step1: Calculate total distance

Distance is the total length of the path traveled. She biked 1.7 miles forward and 0.4 miles back. So we add these values.
$1.7 + 0.4$

Step2: Perform addition

$1.7+0.4 = 2.1$ miles

Step3: Calculate displacement

Displacement is the straight - line distance from the starting point to the ending point. She moved 1.7 miles forward and 0.4 miles back. So we subtract the distance she moved back from the distance she moved forward.
$1.7−0.4$

Step4: Perform subtraction

$1.7 - 0.4=1.3$ miles

Answer:

Distance: 2.1 miles
Displacement: 1.3 miles
