Question

after the interview ,Ellen decided to hire two of the applicants and reject the others .Ellen's assistant called back the applicants to tell them the result . she spent 1/30 of an hour calling each of the rejected applicants and 1/3 of an hour calling the hired applicants .how much time did the assistant spend making these calls?

Answer 1

Answer:

40 + 2r

Step-by-step explanation:

Well an hour has 60 minutes.

So 60 x 1/30 = 60/30 = 2 minutes for each person that didn't get into the job

60 x 1/3 = 60/3 = 20 minutes for the people that made it into the job.

20 x 2 = 40 minutes in total for the people that made it into the job.

We don't know how much people got rejected so:

The answer is

40 + 2r
