Every 60 days.

Step-by-step explanation:

This is very similar to a sequence.

try starting out with:

Abe: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21

Barb:  2, 4, 6, 8, 10

Carl:  3, 6, 9, 12

Dee:  4,8, 12, 16, 20, 24, 28, 32, 36

Earl:  5, 10,

so If today they all worked together

We need a common multiple of  5, 4, 3  so  it is 60

It appears that it will be in 60 days
