Question 845468: Melina's typing speed is 36wpm. She finishes a job in 5 hours. How long would the same job have taken her if she typed 48wpm?
I tried it like this:
36wpm = 5hrs
12wpm(/3) = 15hrs(*3)
48wpm(*4) = 3.75hrs(/4)
Is there a more reliable solution, one with algebra pehaps? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Rate*Time=Output
I think you've got the gist of it. is the constant for output.
So any product of rate and time must equal
