Three microphones recorded an explosion. The sound reached the microphone at site A 2.5 seconds later than it reached the microphone at site B and 1.6. seconds later than it reached the microphone at site C. Sites A and B are 1.5. miles apart. Sites A and C are 0.75 miles apart. Sites B and C are 1.3. miles apart. Site B is N 75 degrees E of site A and site C is S 45 degrees E of site A. Estimate the location of the explosion to within 10 feet by giving distance and direction from site A. (Assume sound moves at 1100 ft/sec).    We have been talking about hyperbolas in class if that helps.

Three microphones recorded an explosion. The sound reached the microphone at site A 2.5 seconds later than it reached the microphone at site B and 1.6. seconds later than it reached the microphone at site C. Sites A and B are 1.5. miles apart. Sites A and C are 0.75 miles apart. Sites B and C are 1.3. miles apart. Site B is N 75 degrees E of site A and site C is S 45 degrees E of site A. Estimate the location of the explosion to within 10 feet by giving distance and direction from site A. (Assume sound moves at 1100 ft/sec).
