The average speed can be calculated by taking the harmonic mean of the two speeds.

• To calculate the harmonic mean, divide the sum of the speeds by the reciprocal of the sum of their reciprocals.

• In this case, the harmonic mean can be calculated as 2/(1/20 + 1/30) = 24 km/h.

The minimum number of steps to find the defective ball is 2.

• Divide the 8 balls into 3 groups of 3, 3, and 2 balls.

• Compare the weights of the two groups of 3 balls.

• If one group is heavier, divide it into 2 balls and compare their weights.

• If the two balls have different weights, the heavier ball is the defective one.

• If the two balls have the same weight, the remaining ball in the first group of 3 is the defective one.
