1.	a boy's 60 m in front of a wall and claps the boy continuous to clap every time and echo is heard another boy. The time taken between the first and fifty First Club is 20 s calculate the speed of sound
Answer» ed of SOUND will be 300 m/sExplanation : Distance between the boy's HAND and wall = 60 mTime between 1st and 51ST CLAP's echo = 20 secTotal echo between 1st and 51st clap = 51 - 1 = 50Hence distance covered by sound = 50 x 60 x 2= 6000Hence speed = distance by time=> s = 6000/20 = 300 m/sHence speed of sound will be 300 m/s
