Kai was 200 meters north from his house when he remembered he had to take some books to the library. it took him 200 seconds to do the round trip. which best describes kai’s roundtrip?

Kai was running at the speed of 2 meter per second and the value of velocity is 0

Step by step explanation:

It is given that the distance between kai and his house is 200 meter. He remembered he had to take some books to the library. It took him 200 seconds to do the round trip.

He travel from his current location to his house after that he reach his current location.

Total distance covered by him is

Total time take by him is 200 seconds.

The formula of speed is

The formula of velocity is

Since Kai reached his current location therefore the displacement is 0.

Therefore, the speed of Kai was 2 meter per second and the value of velocity is 0.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

since there are no options posted i'll give you a few examples.
