【Observation】
I stay in the dorm called “Branner Hall”. It has a nice green yard outside. In Satarday morning, seeing the outside from the window, I found a gardener coming in with blower in his hands. He started to blow the fallen leaves out of the passways. After 5 minutes, seeing around the plants to check if leaf-cut is needed or not. Judging that he does not have to cut leaves on that day, he left the garden. All of it spent him about 10 minuites. in
【Context of the problem】
As you see, Stanford has a large amount of plants and glass which requires regular mentainance in the 32.5 hundred thousand square meters campus. Thus, it requires gardeners to do much tasks to complete. Those tasks include blowing fallen leaves aside, trimming the plants,triming the glass. However, this work can be extremly tough in the summer time, since thhe gardeners have to put up with heat.
