What do all of the examples have in commonUsing what's given below, answer the following parts for practice: Ansdrew needs to get produce from the store, which is a distance d=2.87 km east of his condo. Andrew rides his bicycle to the store at a constant speed of v1= 6.19 m/s, and rides back to his condoat the slower speed of v2=2.22 m/s. The figure below is not drawn to scale. Part A: How long, in seconds, does it take for Andrew to reach the store? And how long in both seconds and minutes does the whole trip take? Part B: What total distance, in kilometers, was traveled by Andrew during the whole trip? Part C: What is the magnitude, in kilometers, of Andrew's displacement for the entire trip and what was the direction of his displacement for the entire trip?
