A group of 5 craftsmen, working together at the same rate, can finish a job in 3 hours. How long will it take a group of 4 apprentices working together to do the same job?
1) each apprentice works at 2/3 the rate of a craftsman.
2) The 5 craftsmen and the 4 apprentices working together will take 45/23 to finish the job.
Answer is D.
1) does "A group of 5 craftsmen, working together at the same rate, can finish a job in 3 hours" translate into w=RT ----> (1/5) = R3-------> 1/15=R
Is that correct, setting W equal to 1 over the number of workers? If not, how do i translate that to find the rate of one craftsman
2) what does 45/23 mean. does that mean "45 parts of the job every 23 minutes?
can you please show algebraically using w=rt how statement 2 is sufficient.
thanks. i really need help understanding this. i need to get to a point where im not confused about how to translate sentences into w=rt so I can knock these type of questions out fast.
