Answer:1)24 days
2)8 days
Step-by-step explanation:
1)In 1 day : A can do 1/40 of the work
B can do 1/60 of the work
Combined in 1 day: A and B can do 1/40+1/60 = 5/120 =1/24 of the work
Therefore, they take 24 days to complete the work if they work together.
2)To complete 1/3 of the work they take 1/3*24=8 days.
