Question

Perry can fill a sorter with oranges from the conveyer belt in 10 minutes. While Perry fills the sorter, Gillian takes oranges out of the sorter and puts them in shipping crates. With Gillian taking oranges out of the sorter, it takes 25 minutes for Perry to fill the sorter.

Which of the following can be used to determine the amount of time it takes for Gillian to empty the sorter if Perry does not add oranges?

Answer 1

1 over 10 minus 1 over x equals 1 over 25
1 over 10 minus 1 over 25 equals 1 over x
1 over 25 minus 1 over x equals 1 over 10
1 over 10 minus 1 over x equals x over 25

Answer 2

Answer 3

ok another one for the books
i think they want you to solve via
\[\frac{1}{20}+\frac{1}{x}=\frac{1}{25}\] that is my best guess
can you provide me with the name of the person who wrote this?

Answer 4

sorry, typo i meant
\[\frac{1}{10}+\frac{1}{x}=\frac{1}{25}\]

Answer 5

Thanks you:0

Answer 6

Try Xavier high school loll

Answer 7

Wait, I think it's B?

Answer 8

i think it is A

Answer 9

but like i said i wouldn't bet on it

Answer 10

1/10 - 1/x =1/25 ?

Answer 11

Nah, I believe you :)

Answer 12

actually i think you might be correct

Answer 13

Thanks so much for all your help!

Answer 14

Don't doubt yourself! I think you're right, now that I look at the question.

Answer 15

if you solve
\[\frac{1}{10}+\frac{1}{x}=\frac{1}{25}\] you get a negative answer of \(-\frac{50}{3}\) whereas if you solve with a minus sign you get \(\frac{50}{3}\) so it depends on whether you want a negative of positive answer
my guess is B now too
