Question

Problem 3: Locating Whales
Hyperbolas can be used to locate objects underwater. To locate a whale in the ocean, two microphones are placed 8000 feet apart. One microphone picks up a whale noise 0.4 seconds after the second microphone picks up the same noise. The speed of sound in water is about 5000 feet per second.
a. How much farther from the whale is the first microphone?
b. Find an equation for the possible locations of the whale.
c. What is the closest distance that the whale could be to the second microphone?
d. Will the whale always be closer to the microphone that receives the signal first? Can the whale be on either branch of the hyperbola? Explain your reasoning.
