Answer 1

uff = Given

Han can stuff 20 envelopes in one minute

Clare can stuff 10 envelopes in one minute

Together they start working on a pile off 1000 envelope.

Find

How long does it take them to finish the pile.

Step-by-step explanation

as we have given

in one minute , Han can stuff = 20 envelope

in one minute , Clare can stuff = 10 envelope

together in one minute , they can stuff =

`\begin{gathered} 20+10=30 \\ \\ \end{gathered}`

we know that the number of time it will take to finish stuffing would be number of envelope / joint rate = 1000/30

so , time taken to finish the pile =

`\begin{gathered} (1000)/(30) \\ \\ (100)/(3) \\ \\ 33(1)/(3) \\ or \\ 33min20sec \end{gathered}`

Final Answer

Hence , the time taken by them to finish the pile is 33 minutes 20 seconds
