Answer:
41.52 m
Explanation:
Using,
v = d/t....................... Equation 1
v = speed of pulse of sound, d = distance travelled by the pulse of sound, t = total time taken.
From equation 1, make d the subject of the equation
d = vt............................ Equation 2
Given: t = 0.12 s.
Constant: v = 346 m/s
Susbtitute these values into equation 2
d = 346(0.12)
d = 41.52 m
