An experiment is performed to determine how bats capture insects in the dark. A pair of microphones are set up on either end of a long room with the bat being released on one end and an insect on the other. When the bat begins to chase the insect, the microphone near the bat hears a frequency of 79.79 kHz and the microphone on the other side of the room hears a frequency of 81.63kHz. a) (3pts) What is the speed of the bat
