You can put this solution on YOUR website!
You investigate how long it would take you and a friend to fold 1000 origami cranes.
You take 2 minutes to fold 1 crane.
Therefore your rate is (1/2) crane/minute
------------------------------------------
Let x represent the number of minutes it might take a friend to fold 1 crane.
Then her rate is 1/x crane/minute
--------------------------------------
Question: The expression 60/1000x is your friend's work rate per hour. Explain why.
(1/x)(crane/min)(60 min/1 hr) = 60/x (crane/hr)

Comment: I don't agree with the 60/1000x answer.
