Question

Adonis, Joshua, Noel worked together to finish a painting job. Joshua worked 8 less than Adonis. Noel worked twice as long as Joshua. If together they worked 72 hours on the Job, many hours did Noel work?

Answer 1

Let the number of hours Joshua worked be `x`.

Number of hours Joshua worked: `x`
Number of hours Adonis worked: `x+8`
Number of hours Noel worked: `2x`

`x+2x+x+8=72`
`x+2x+x=72-8`
`4x=64`
`x=16`

If `x=16`,

`2x=2xx16`
`2x=32`

Hence, Noel worked 32 hours.
