Kia was 200 m north of the Liebrary when he remembered he had to return some books to the library it took him to 200 seconds to do the round-trip which best describes cost round-trip

His speed is 2 m/s

His velocity is 0 m/s

Step-by-step explanation:

I'll assume the question is

Kia was 200 m north of the Library when he remembered he had to return some books to the library it took him to 200 seconds to do the round-trip which best describes hist round-trip.

Kia's distance from the Library is 200 m

the round-trip took him 200 s

The total distance for the round trip = 200 x 2 = 400 m

His displacement for the round trip = 0 m (since he returns to his original position)

His speed = distance/time = 400/200 = 2 m/s

His velocity = displacement/time = 0/200 = 0 m/s
