Teacher Li drove a private car to Hefei Painting and Calligraphy Academy to see the painting exhibition. He left home at 8:00 am and arrived at the Academy of Calligraphy and Painting at 3:00 pm. If the car travels 75 kilometers per hour, please help me to calculate, how many kilometers is the distance from Mr. Li's home to Hefei Painting and Calligraphy Academy?
