6.8
The correct answer is 6.8.
The ratio between them is constant ($y = kx$). Inverse Proportion: Two quantities are inversely proportional if an increase in one leads to a proportional decrease in the other, and vice versa. Their product is constant ($xy = k$). Understanding proportionality helps in solving problems involving ratios, scaling, speed-distance-time, work, and many other quantitative relationships.
