The correct option is C) The angle between the vectors is 120°.
Why?
We can solve the problem and find the correct option using the Law of Cosine.
Let A and B, the given two sides and R the resultant (sum),
Then,

So, using the law of cosines, we have:

Hence, we have that the angle between the vectors is 120°. The correct option is C) The angle between the vectors is 120°

Explanation:
Average speed of car = 5m/s
Distance run by dog = 20m
Time taken = 5s
problem;
does the dog catches the car = ?
Solution;
let us determine speed of the dog;
Speed =
= 4m/s
The average speed of the car is 5m/s
Average speed of the dog is 4m/s
The dog is slower than the car and it will not catch the car at this rate.
