Question

If 15 workers can build a wall in 48 hours, how many workers will be required to do the same work in 30 hours

Answer 1

9 workers

Explanation:

15 workers = 48 hrs build

x workers = 30 hrs build

cross multiply

15 × 30 = x × 48

450 = 48x

x =

`(450)/(48)`

x = 9.37

so it will take approximately 9 workers to build a wall for 30hrs
