The distance between the boy and the hillock is 170 metres, calculated by dividing the total distance covered by the sound (to and fro) by two.
A boy shouts loudly in the direction of a flat hillock located some distance away. The echo of the shout reaches back to the boy in 1 second. If the speed of sound is about 340m/s due to weather conditions, what is the distance between the boy and the hillock?
