Physics calculation from grade one to grade three When shooting, the distance between the target and the shooter is 300 meters. After shooting for 1.4 seconds, the shooter hears the sound of hitting the target, and the sound speed is 300 meters per second. Calculate the average flight speed of the bullet

Physics calculation from grade one to grade three When shooting, the distance between the target and the shooter is 300 meters. After shooting for 1.4 seconds, the shooter hears the sound of hitting the target, and the sound speed is 300 meters per second. Calculate the average flight speed of the bullet

300/300=1s 1.4-1=0.4s 300/0.4=750m/s
