Answer:16m from alphabet chart
Explanation:
If the patient is 3m away from mirror and alphabet chart is 5m away from patient, then alphabet chart will be 8m (5m+3m)away from mirror. As image distance is equal to object distance, then image formed will be 16m away from the alphabet chart and 13m (16m-3m) away from patient.
