उत्तर
36 km/ hr can be converted into m/ s to compare with 8.5m/ s.
36 km/ hr = {36 x 1000) / 3600 = 10 m/ s which is greater than
8.5 m/ s So 36 km/ hr is greater than 8.5 m/ s.

A girl had designed a clap switch for a science exhibition that enabled her to switch on or off an alarm just with clapping of hands. While testing her device in a hall, she noticed that once the alarm has sounded it followed with another one due to echo of the clap, that is, the sound reflected by the walls. She recorded the two soundings of alarm with her tape recorder and found out that time difference in between them is 0.1 s. If the distance of the walls be 15 m, calculate the speed of sound.
