Question:
I saw this problem in a magazine....I am stumped.
Joan and Jan work together and they set up a bandstand in just 24 minutes, but if Joan does it by herself she takes 1 hour. How long would it take Jan to set up the bandstand by himself?
Hi Karyna,
Joan and Jan work together and they set up a bandstand in just 24 minutes,
So, they could set up 5 bandstands in 5*24 minutes, that is, 2 hours.
but if Joan does it by herself she takes 1 hour.
So, in 2 hours, Joan could set up 2 of the 5 bandstands,
leaving the other 3 to Jan.
How long would it take Jan to set up the bandstand by himself?
Can you find it now?
