For a project, team a will do it alone for 10 days and team B will do it alone for 15 days______ Half of the project can be completed in one day

For a project, team a will do it alone for 10 days and team B will do it alone for 15 days______ Half of the project can be completed in one day

12 (110 + 115), = 12 (16), = 3 (days); a: half of the project can be completed in 3 days

A project will be completed in 10 days by Party A and 15 days by Party B. the cooperation between the two teams will take several days to complete

Suppose that the project can be completed in X days (1 / 10 + 1 / 15) × x = 1, x = 1 △ 1 / 6, x = 6, a: the cooperation between the two teams will take 6 days to complete,
