Answer:
The other end of the pool is 11.25 m far away
Explanation:
Wave: A wave can be defined as a disturbance that travels through a medium and transfer energy from one point to another without causing any permanent displacement of the medium itself.
Velocity of wave (v) = 2x/t............................. Equation 1
making x the subject of the equation,
x = vt/2
Where x = distance, t = time.
Given:v = 0.75 m/s, t = 30 s.
Substituting these values into Equation 1,
x = (0.75×30)/2
x = 11.25 m.
Therefore, The other end of the pool is 11.25 m far away
