B-19.5 m/s
C-28 m/s
D-21.5 m/s
If the velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration, the average velocity of the body is 21.5 m/s. the answer is letter D. Velocity is a vector quantity and average velocity can be defined as the sum of the initial and final velocity divided by 2 at constant acceleration.
