Given the stream of consciousness rationale, provide a reasonable question and answer. Rationale: Robert coughs twice as much as Georgia who coughs 5 times so Robert coughs 2 * 5 = 10 coughs per minute. Georgia coughs 5 times and Robert coughs 10 times so together they cough 5 + 10 = 15 times per minute. After 20 minutes they will have coughed 15 * 20 = 300 coughs.
 The question and answer:
Georgia is sick and coughs 5 times a minute. Her brother Robert is also sick but he coughs twice as much as her. After 20 minutes, how many times have they coughed?
The answer is 300
