The depth of a pond is determined by a scientist using a sonic ranger. It
takes 0.02 seconds for the sound waves to travel to the pond's bottom
and back to the boat. The sound waves were reported to be traveling at
1210 m/s. How deep is the pond in meters? *
O 12.1
O 24.2
O 6.3
O 3

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
