Cars, trucks, and buses use petroleum—which is a fossil fuel—to power them. Mrs. Cash has a class of 20 students. Half of her students get rides to school from their parents. The other half take the bus. If it takes the same amount of energy to transport three students to school by bus as it takes to transport one student by car, how could the amount of energy Mrs. Cash's students use be reduced the most?(1 point)
