e) Since Dave starts from house and finally returns to the house so displacement is zero.
Explanation:
Given:
- distance between the house and the store,
- speed of driving from house to store,
- speed of driving back from store to house,
Since the store is located towards east from his house and the velocity in this direction is taken negative and contrary to this the velocity in the west direction is taken positive.

c)
the time taken by the trip in minutes:
d)
distance travelled in the whole trip:
e)
Since Dave starts from house and finally returns to the house so displacement is zero.
I think the correct answer from the choices listed above is the last option. When electrical energy is converted into thermal energy, the <span>total amount of thermal energy plus electrical energy doesn't change. This is base on the Law of Conservation of energy where energy cannot be created or destroyed. </span>
