AV2/(t2-t1)B(V2-V1)/(t2-t1)C(V2-V1)/t2DV2/t2Answer: B. (V2-V1)/(t2-t1)Read Explanation:The average acceleration is (V2-V1)/(t2-t1) Average Acceleration Formula: The formula for average acceleration is the change in velocity, the final velocity minus the initial velocity, divided by the change in time
