Question

MY BRAIN IS DEAD! PLS HELP MEH ITS THE LAST ONE! TYSM! Time taken for 6 people to build a house is 30 days. How many days will it take for 2 people to build the same house ? (You need to think if this is a direct or inverse proportion problem).

Answer 1

90 days

Explanation:

6 people- 30 days

1 person- 30*6= 180 days

2 people- 180/2= 90 days

Answer 2

2 people will take 90 days to complete the same house

Explanation:

Given:

T1 = 30 days

P1 = 6

T2 = x

P2 = 2

This is an inverse proportion because if there are more people, less time will be taken to complete the house and vice versa.

So, We'll write it in the order of :

=> T1:T2 = P2:P1

=> 30:x = 2:6

Writing in fraction form

=>
`(30)/(x) = (2)/(6)`

Cross Multiplying

=> 2x = 180

Dividing both sides by 2

=> x = 90 days

So, 2 people will take 90 days to complete the same house
