【context of the problem】
As you see, Stanford has a large amount of plants and glass which requires regular maintenance 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,and trimming the glass. However, this work can be extremely tough in the summer, especially when they have to continue the work for a long time with tempreture above 30℃.
【Problem statement】
For a gardener on the Stanford campus, it is too hot to do the tasks on summer days. This is because he has to wear long shorts and long pants with whole body in black clothes, while carrying a heavy machine for blowing fallen leaves.
