26.5 metres (87 feet)This was the right answer

There's an eyesight test for the Register of Approved Driving Instructors. The requirement is that an instructor must be able to read a number plate with letters and figures 79 mm high and 50 mm wide at a minimum distance of 26.5 metres (87 feet). This is a greater distance than the minimum legal requirement for car drivers.
