Answer:
24 days
Step-by-step explanation:
in one day
First team construct 1/40 of the bridge
second team construct 1/60 of the bridge
both teams construct (1/40 +1/60) of the bridge = 1/24 of the bridge
therefore
if both teams work together will need 24 days

ANSWER IS 140 DAYS
Step-by-step explanation:
here
20 people=40
25 people=60
therefore,
5 people= 60 -40
= 20
NOW
if both team work together
therefore
total people = 20 + 25
= 45
therefore
days required = 140
(15 people =20
20 people = 40
25 " = 60
30 " = 80
35 " = 100
40 " = 120
45 " = 140 )
