Today we learned about person-days. A person-day is the amount of work a person can do in a day. (1 person x 1 day= 1 person-day). We can do all kinds of fun math word problems with this info. For example, if it takes 8 monsters three weeks to scare 96 children, how many monsters can scare 96 children in 2 weeks? First, we multiply 8 monsters by 3 weeks to determine that it takes 24 monster-weeks to scare 96 children (we multiply, because we are going from monster and weeks to monster-weeks). Then we divide that 24 monster-weeks by 2 weeks and find that it will take us 12 monsters.
8 monsters x 3 weeks= 24 monster-weeks. 24 monster-weeks / 2 weeks= 12 monsters.
Don't worry if it's not 100% clear yet. We'll keep working on this for a while.
Ciao!
