The time for a sound wave to travel between two people is 0.80 s, The people are 256 m apart
Calculate the speed of sound in air.

Explanation:

Using the below formula

Speed of sound = ( distance between observers) *2/(total time taken)

Now putt the given values ,

time taken = 0.80 sec

distance = 256 m

hence

V of sound= 256*2/0.80

V of sound = 640 m/sec

they start with the same

b.
