An automatic focus camera is able to focus on objects by use of an ultrasonic sound wave. The camera sends out sound waves that reflect off distant objects and return to the camera. A sensor detects the time it takes for the waves to return and then determines the distance an object is from the camera. If a sound wave returns to the camera 0.150 seconds after leaving the camera, how far away is the object? (take speed of sound = 330 m/s)
