The study found that viral droplets expelled both in coughs and sneezes travels at speeds that range between 22 miles per hour to 68 miles an hours. This translates to 33 feet per second and 100 feet per second. The speed rate depends upon the strength of the original expulsion and how warm and moist the atmosphere is. The study can be viewed at
