Dave needs to get groceries from the store, which is a distance of D=2.8km east of his house. Dave rides his bike to the store at a constant speed of v1=6.9m/s, and rides back to his house at the slower speed of v2=2.9m/s.

1.) How long (in seconds) does it take Dave to reach the store?

2.) in seconds, how long does the whole trip take?

3.) how long does the trip take in minutes?

4.) How much distance, in kilometers, did Dave travel during the whole trip?

5.) What is the magnitude of Dave's displacement, in km, for the entire trip?

6.) What is the direction of Dave's displacement for the entire trip?
