Sample Activity of Integration on Equation of a Straight Line

During a hot day in a large city of Kampala, the pollution index increases approximately
from 8:00 a.m. to 4:00 p.m. On an average hot day, at 10 a.m., the pollution index is around
43.0 parts per million (p.p.m.) and at 1 p.m., the reading is 80.5 p.p.m. Resource: Knowledge of linear equations and their graphs.

Task
Support:
People in Kampala are told not to jog outdoors if the pollution index is above 100 p.p.m.. Using the pollution index, over an appropriate time span, of Kampala city, write a report advising the people of Kampala who jog on how best to manage their jogging schedule.
