Question 1186546: Two stations, located at A (-1.5, 0) and B (1.5, 0) (units are in km),
simultaneously send sound signals to a ship, with the signal travelling at the speed of 0.25 km/s. If the signal from B was received by the ship four seconds before the signal from A, find the equation of the curve containing the possible location of the ship.

You can put this solution on YOUR website! .
Actually, speed of sound in the air (in the atmosphere) is 343 m/s, or, equivalently, 0.343 km/s.
See this Wikipedia article
https://en.wikipedia.org/wiki/Speed_of_sound
Everybody in the world, who studied Science in Middle school, knows this number,
so it is awkward to me to solve this problem with incorrect input data.
People may think that I am totally illiterate in Science . . .
