To my cousin, who is in high school and asked me for help with this problem on his homework: Why are you asking me for help with math? I’m an art school graduate. Find the smartest person in your class (usually a quiet girl with glasses and long dark hair) and ask them to help you. Don’t laugh; it works.

Look for a girl like this. Such girls are often mathematical.
Anyway, I think this problem is simple enough so I can help you. Just keep my advice in mind for next time. It’s hard to deliver detailed explanations over the internet from all the way here in Seattle, especially when I’m trying to play Toho. Find someone in Chicago to help you.

Problem 25: A car is driven at a constant velocity of 25 m/s for 10.0 min. The car runs out of gas and the driver walks in the same direction at 1.5m m/s for 20.0 min to the nearest gas station. The driver takes 2.0 min to fill a gasoline can, then walks back to the car at 1.2 m/s and eventually drives home at 25 m/s in the direction opposite that of the original trip.
Draw a v-t graph using seconds as your time unit. Calculate the distance the driver walked to the gas station to find the time it took him to walk back to the car.
