Question

On Monday, it took 5 builders 3h 1/2 hours to build a wall.
An identical wall needs to be built on Tuesday but only 2 builders are available.
Each builder is paid £9.30 for each hour or part of an hour they work.

Work out how much each builder will be paid
for the work completed on Tuesday.

Answer 1

8.75 hours is required for completing the work by 2 builders.

Step-by-step explanation:

5 builders need 3.5 hrs for completing the wall.

Therefore no of work hours required= (5×3.5) =17.5 work.

Therefore one builder can complete the work in 17.5 hours.

Therefore 2 builders can complete the work in (17.5/2) hours=8.75 hours.
