It is strongly recommended that every student should walk to school.Yesterday,I investigated the way that every student in a class in our school goes to school.The class has fifty students.Three tenths of the students in the class go to school by bus and one fifth of them walk to school.One half of the students go to school by bike but none of the students go to school by car.
