It takes 50 people 256 days to build a road. How long will it take 80 people, assuming that everyone works at the same rate?
Answers
Answer:
415 days for 80 people
Step-by-step explanation:
divide 256 by 2 which is 132.5 then add 25 people to the 50 which is 75
and 256 + 132.5 = 388.5 then divide 256 by 10 and you get 26.5
then add 388.5 and 26.5 and you get 415.
good luck.
Answer: It will take 160 days for 80 people.
Step-by-step explanation:
p= 50 people, T=256 days
The number of days is inversely proportional to the number of people:
T ∝ 1/p
T = k/p
We'll now replace T and p with its values:
256 = k/50
256 × 50 = k
k= 12,800
We'll now rewrite this (T = k/p) as an equation:
T = 12,800/p
We need to know how much days would it take if the amount of people is 80. By using our newly- formed equation, we'll find out the answer:
T = 12,800/p
T = 12,800/80
T = 160
Therefore, it will take 160 days if 80 people builds a road.
Hope this helps!
