A sound note of frequency 250 Hz and wavelength 1.3m is produced at a point near a hill. If the echo of the sound is received 1 second later at the point, how far away is the hill from the point?

ECHO...=V=2D/T WHICH IMPLIES... 250*1.3/2=162.5 PLZ MY SCHOOL

f=250HZ,wave length=1.3,t=1s.V=f times wavelength.250 times 1.3=325m/s.V=2x/t.325=2x/1.2x=325.x=325/2=162.5m ans.
