Answer:
they work together, it will take 2.4 hours to build the wall.
Step-by-step explanation:
One bricklayer can build a wall in 6 hours.
One hour work = ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
Another bricklayer can build the same wall in 4 hours.
One hour work = ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
They can together, how long will take them to build the wall.
Let's take "t" the time taken to build the wall.
The sum of their work rate = 1 (To build the wall)
![\frac{t}{6} + \frac{t}{4} = 1](https://tex.z-dn.net/?f=%5Cfrac%7Bt%7D%7B6%7D%20%2B%20%5Cfrac%7Bt%7D%7B4%7D%20%3D%201)
Now we have to solve this equation. Take LCD of 6 and 4.
The LCD (least common divisor) of 6 and 4 is 12.
![\frac{2t + 3t}{12} = 1](https://tex.z-dn.net/?f=%5Cfrac%7B2t%20%2B%203t%7D%7B12%7D%20%3D%201)
5t = 12*1
5t = 12
Dividing both sides by 5, we get
t = ![\frac{12}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B5%7D)
t = 2.4 hours.
So, they work together, it will take 2.4 hours to build the wall.
