Using thin-layer chromatography showed that the black dye used in a brand of writing ink contained blue, red, orange and yellow components. The Rf values of these substances using ethanol as the solvent are 0.63, 0.37, 0.79 and 0.16, respectively. How far apart would the blue and yellow components be after the solvent front had moved 7.5 cm from the origin?
