What is the average velocity between 12.00 and 15.00 seconds?
a) 81.0 m/s, east
b)27.00 m/s, east
c)9.00 m/s, east
d)0.0123 m/s, east

The velocity of abject in a given time interval from 12 seconds to 15 sec is 27 m/s.

Explanation:

Displacement of the object after 12.00 seconds = 144 m

Displacement of the object after 15.00 seconds = 225 m

The velocity of abject in a given time interval from 12 seconds to 15 sec is 27 m/s.
