Last Friday's problem

January 9 hints and answers

A certain king sent 30 men to plant trees. If they can set out 1000 trees in 9 days, how many days would it take for 36 men to set out 4400 trees?

To solve this one, it will probably help to figure out how many trees one man can plant in one day. Then go from there. Don't be afraid of the fractions that come up!

As always, be sure to explain the work you did to arrive at your answers!
