Mowing the Grass Four friends volunteered to mow the grass around their neighbor's house. They decided to split the job up into
weeks instead of everyone mowing the grass on the same day. On week 1, Jay mows the grass at a rate of 25%
every 30 minutes. On week 2, Amy mows the grass at a rate of 3 of the grass every 30 minutes. Week 3, Ken
mows at a rate of 0.3 of the grass, every 30 minutes. It takes Brittany 2.5 hours to mow all of the grass on week
4. Determine how long it takes each person to cut all the grass. Who was the fastest?
