D Correct answer
Explanation

Average speed depends on the distance covered at each speed. Since the problem does not specify the distance covered at each speed (e.g., is it half the distance or half the time?), the average speed cannot be determined.

B Correct answer
Explanation

A speed = D/8. B speed = 1.2 * (D/8) = 0.15D. B distance = 0.8D. Time t = Distance/Speed = 0.8D / 0.15D = 80/15 = 5.33 hours. Since 5.33 < 6, Quantity B is greater.
