Question

The first bricklayer can build a wall in 15 days, and the second bricklayer can build the same wall in 10 days How long will it take for them to build the wall together?

Answer 1

Answer:

It will take both of the brick layers twelve and half days

Answer 2

6 Days

Step-by-step explanation:

First you must find the combined rate of work per day between the two bricklayers.

(100/10)+(100/15) = 16 2/3

For each day the two bricklayers complete 16 2/3 percent of the work. To find out the amount of days it take them to build the wall you divide 16 2/3 from 100

100/16 2/3 = 6

The amount of days it take the two bricklayers to build the wall together is 6.
