Answer:

THE DISTANCE OF THE ROCK REFLECTING HER VOICE IS 82.5 METERS.

Step-by-step explanation:

In sound waves, the speed of a sound is equal to twice the distance divided by time.

Mathematically,

Speed = 2 * Distance/ Time

Speed = 33- m/s

Time = 0.5 second

Distance = unknown

So re-arranging and introducing the variables into the formula, we have;

Distance = speed * time / 2

Distance = 330 * 0.5 / 2

Distance = 82.5 meters.

The distance away from the rock face which is reflecting her voice is 82.5 meters.
