Question

Before COVID-19, I would drive my son across town to school every weekday. In doing so, I must estimate how long the drive will take, depending on the time we leave the house. The journey takes around 20-minutes without traffic. If we leave our house between 0724 and 0730, we should arrive at the school around 0745 and 0750. However, if we are to leave anytime after 0731, we will hit rush hour traffic, which will extend our travel time by an additional 10-30 minutes. Luckily, we are usually out the door before 0730 and arrive at the school around 0750-0755. I have included approximate travel times for last week's travel.

Approximate Travel Times for the Week of March 8, 2020

Monday 0724-0745 (21 min.)
Tuesday 0727-0748 (21 min.)
Wednesday 0725-0750 (25 min.)
Thursday 0730-0755 (25 min.)
Friday 0726-0748 (22 min.)
