Question

3) An engineer working in a mine is overseeing two detonations that go off at exactly 8:00 am. The engineer hears the two blasts at 4 seconds and 6 seconds after 8:00 am, respectively. The angle between her lines of sight to the two detonation sites is 50°. If sound travels at 344 m/s, how far apart are the two detonations?

00:01 Okay, today i'll be going over question number 56, which talks about two factories.
00:05 They blow their whistles.
00:09 There's a man that hears the whistle and tells you the angle and also how far sound travels.
00:17 So to find out how far away the man is from each factory, you would do 344 times how many seconds.
00:34 So the first one is three seconds, which gives you 1032 meters.
00:41 And then the one that is six seconds...
