20m per second, because the difference between -50 and 250 is 300, and just divide 300 by 15, because distance/speed.

Answer 2

A car moves from position 50m south of the library to new position 250m north of the library this movement takes 15 seconds what is the velocity of the car

Explanation:

The equation is displacement/time = (250 + 50) m/ 15 s = 20m/s.

The answer is: 20m/s.
