Georgia coughs 5 times a minute, so in 20 minutes, she will cough 5 * 20 = 100 times.
Robert coughs twice as much as Georgia, so he coughs 5 * 2 = 10 times a minute.
In 20 minutes, Robert will cough 10 * 20 = 200 times.
Together, Georgia and Robert will cough 100 + 200 = 300 times in 20 minutes.
#### 300
The answer is: 300
