A small quantity of compound A was applied to the mid-point of the following TLC plate’s line of application (drawing is not to scale). After development of this plate by a suitable solvent, compound A was determined to have an Rf value of 0.35. Once the solvent had evaporated from the TLC plate it was re-developed using the same solvent as before. What distance (in mm) did compound A travel during the second development? Please carry maximum number of significant figures through to final answer then round to one decimal place. Do not include units.
