One bricklayer can build a wall in 6 hours. another bricklayer could build the same wall in 4 hours. if they work together, how long will it take to build the wall?

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 =

Another bricklayer can build the same wall in 4 hours.

One hour work =

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)

Now we have to solve this equation. Take LCD of 6 and 4.

The LCD (least common divisor) of 6 and 4 is 12.

5t = 12*1

5t = 12

Dividing both sides by 5, we get

t =

t = 2.4 hours.

So, they work together, it will take 2.4 hours to build the wall.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

.95
