- You Are Out In A Park When Suddenly A Dragon Appears Terrified As You Should Be You Start Running Away From The Drago 1 (17.78 KiB) Viewed 56 times
You are out in a park when suddenly a dragon appears. Terrified (as you should be) you start running away from the dragon at 2.80 m/s. As it starts to charge towards you it lets out a terrifying screech that you hear at 1,389 Hz. Knowing that dragons can screech at 1,251 Hz, how fast is the dragon moving? Take the speed of sound in air to be 343 m/s.
