Question

an eco return in 3 second what is the distance of reflecting surface from the source given that the speed of sound is 342 M per second

Answer 1

Heya.....!!!!

____________________________

Given :-

• Time = 3 sec
• Speed of sound = 342 m/s

• Distance = ??

We can solve this question easily by applying the formulae :- v = 2d/t

=> v = 2×d/t

Putting the values we get ,, :

=> 342 = 2×d/3

=> d = ( 342 × 3 ) ÷ 2

=> d = 1026 ÷ 2

=> d = 513 m is the answer .
