Question

On Monday, it took 5 builders 3 in a half 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

£83.70

Explanation:

→ First step is to find the amount of hours it takes for one builder

We know it takes 5 builders
`3(1)/(2)` hours so 1 builder would take 5 ×
`3(1)/(2)` which is
`(35)/(2)` hours so it takes one builder 17.5 hours to builder a wall

→ Now we know how long one work takes we need to find out the time for 2 builders

1 builder = 17.5 hours

2 builders = 17.5 ÷ 2 = 8.75 hours

So 2 builders take 8.75 hours

→ We know that each builder is paid £9.30 for each or part hour they work so

9.30 hourly pay rate × 9 hours work of work = £83.70

Each worker will be paid £83.70
