Assuming you have the data in a table as in your picture, create a calculated column like this:

AvgerageDaysInbetween = 
var thisCustomer = [Customer]
var temp = 
SUMX(
    FILTER(
        SUMMARIZE(
            'Table';
            [Customer];
            "avg";  
                DIVIDE(
                    DATEDIFF(MIN('Table'[DateOfOrder]); MAX('Table'[DateOfOrder]); DAY);
                    DISTINCTCOUNT('Table'[DateOfOrder])-1;
                    0
            )
        );
        [Customer] = thisCustomer
    );
    [avg]
)
return
temp

Resulting table:
