I need help with this physics problem and I was wondering if you could explain step-by-step, so I don't just get an answer. I really would like to understand it. The French train in the example problem is traveling 301 km/h. When it is 360m from a road crossing, the engineer blows the whistle. If the speed of sound is 330 m/s, how many seconds after the whistle is heard at the crossing will the train cross there?
