Question

It takes 7hrs for 5 cooks to prepare dinner. How long will it take 6 cooks to prepare a dinner?

Answer 1

too many cooks spoil the Broth!

Answer 2

7/5 = x/6
cross multiply for 5x = 42
x=8 and 2/5
so 8 hours and 24 minutes
but this problem doesnt really make much mathematic sense since cook time would be the same...

Answer 3

Its actually 5.8 hrs

Answer 4

how did you get that???

Answer 5

Thats what my program said was the correct answer

Answer 6

well your program needs to show work!

Answer 7

First we can assume that it will take less than 7 hrs, can't we?

Answer 8

If it takes 7 hours for 5 cooks to cook dinner, it takes 35 man-hours to cook a diner.
35 man-hours over 6 cooks is 35/6 hours to cook diner using 6 cooks.

Answer 9

Thanks robtobey, that would work out to be about 5.8222 hours, which indeed is less than 7.

Answer 10

I mean 5.8333 hrs

Answer 11

Which so happens to agree with Needzhelp77.

Answer 12

@ radar I believe you are one of the very early problem solvers on this site. Wasn't it great in the old day when there were only 1500 students?

Answer 13

Yes, it seems to be a furious pace (just to keep up).

Answer 14

Geez, I just saw the number, 22,386 students!

Answer 15

I think today may be my last day here for a variety of reasons. Can't deal with the text talk and ambiguous problem statements. Very difficult to get medals now because there is some one hovering over a key board, transfixed on a computer screen waiting for the next problem to be posted. At least I think I got one problem right that no one even attempted. Refer to: http://openstudy.com/groups/mathematics#/groups/mathematics/updates/4e4a90dc0b8b9588048f0086

Answer 16

Had to go and look at that link, I see no further comment, so it is more than likely correct. It is above my pay grade. I am reviewing these problems to sort of refresh my memory. I am retired now and I don't have to do any math anymore, but still like to dabble if you know what I mean.

Answer 17

Same here. By the way, I may be one of the oldest seniors here. Turned 77 on aug 10.

Answer 18

Sorry to see you go, as I recall you have been very helpful and guided many students. Concur with the hovering, sometimes I think the award system can be harmful. I would rather take time with one student than provide a 100 students with just an answer.

Answer 19

You might pass on your thoughts to the site management via the openstudy feedback.

May check in on occasion.

Adios.
