Answer: 24.2
Explanation:
Given that:
Time taken for sound travel = 0.02 seconds
Speed of traveling sound wave = 1210 m/s
Depth of pond = ?
Recall that speed is obtained by dividing the distance covered (depth travelled) by the time taken.
Hence, speed = (depth travelled / time taken)
1210 m/s = depth travelled / 0.02 seconds
Depth travelled = 1210 m/s x 0.02 seconds
Depth travelled = 24.2 m
Thus, the pond is 24.2 metres deep
