Xiao Ming took the bus to school at a speed of 40km/h, while he walked at a speed of 5km/h. Assuming that it usually took Xiao Ming 40 minutes to get to school by car, Xiao Ming walked for 20 minutes before getting on the bus that day. The problem now was, if Xiao Ming didn't walk and waited at the bus stop where he usually got on, would it be faster to get to school than if he walked and took a bus halfway? How much faster?
Based on the given information, we can calculate that the distance Xiao Ming walked was 5km/h * 20 minutes = 1km. The distance by car was 40km/h * 20 minutes = 13.33 km. Therefore, if Xiao Ming didn't walk but waited at the bus stop, he would reach school faster than walking and then taking a bus halfway. It was 13.33km -1km = 12.33km faster.
Therefore, if Xiao Ming didn't walk and kept waiting at the bus stop, he would reach school faster than if he walked and took a bus midway. It was 12.33km faster.
