What is the safe distance to avoid getting Covid-19?

Netflix recently released a set of "safety distance pics of the epidemic" adapted from Marriage Story stills.

Netflix reminded the public during the epidemic that the divorced couple in the picture should be consulted to keep a proper distance on different occasions.

In the film, Adam Driver and Scarlett Johnasson play a couple who are facing divorce and are facing divorce. The relationship between the two is cold and alienated.
