If you could speed up the other sound, for example by moving towards it, you could get to hear it sooner.

At 330 m/s, it would take 17 min.

At (say) 660 m/s it would take 8.5 mins (double the speed and halve the time)

So, I can figure that the relative speed should be 330 * (17/16.5) = 340 m/s

In other words, at 340 m/s, it would take 17 * 330/340 = 16.5 mins.

So, you would have to "speed up" the sound by simply moving towards it at 10 m/s

]]>Two guns were fired from the same place at an interval of 17 minutes but a person in a train approaching the place hears the second report 16 minutes and 30 seconds after the first . supposing that the sound travels at the speed of 330 mts per second , find the speed of the train
