If a normal secretary can type 80 words per minute, how many hours would it take 3 secretaries to type 36,000 words

Hey!

Hope this helps...

Okay to answer this question we are assuming ONE major thing, that ALL 3 secretaries are considered "normal secretaries", and that they ALL type 80 words per minute...  Now after assuming that, here is some stuff we know...

Each Secretary types 80 words per minute...

We need to find how long it would take them to type 36,000 words...

By knowing this information, we can now proceed to the problem at hand...

80 * 3 = 240 words written (on average) per minute

36,000 / 240 = 150 minutes to write 36,000 words

150 / 60 = 2.5 hours to write 36,000 words

2.5 hours Converts to: 2 hours and 30 minutes

So...

The answer is, It would take 3 secretaries, 2 hours and 30 minutes to write 36,000 words

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
