Here is the riddle.

If a person was walking through a forest, and 2 planes crashed 20 miles away from him at the exact second, which plane would he hear first as soon as they crashed?

 

[Alil2Good]

a person can't hear a plane that's 20 miles away

 

[Country Girl]

um......both at the same time?

or the louder one......?

 

[Urban_M86]

that person would only hear the combination of the 2 sound into a 1 major BBOOOMMM!!!! unless he or she is deaf

 

[cutie]

he'll hear them at the same time

or

he'll hear neither because its 20 miles away ...

 

[Priya V]

I would say both. because both came at the same time.

 

[Logan]

he would only hear one... they crashed exact second and 20 miles away...
