Explanation:
Let's assume that the student is standing at a distance x from the building.
The sound of his clap travels x metres to reach the building, and x metres again to reach the ears of the man, which leads to him hearing the echo. So, total distance travelled by the waves (sound) is 2x. Time taken is 2s. Speed of sound is 340 m/s.
The data we have is: Distance: 2x meters
Speed:340 m/s.
Time: 2s.
Distance Speed x time
2x = 340 x 2
x = 340m
Therefore, the distance is 340m.
