Question

a gun is fired at a distance of 1.7 km away from alok. alok hears a sound 5 seconds later. find the speed at whichthe sound travels

Answer 1

1.7 km = 1700 m
So we divide 1700\5= 340

Answer 2

Sound travels at a speed of 340 m/s.

Distance between Alok and firing (D) = 1.7 km = 1700m      [1km = 1000m]

Time taken for the sound to reach his ears (T) = 5s

We know,

Speed (S) = D / T.

Thus, speed of the sound is = (1700m) / (5s) = 340 m/s.
