The Speed By Which A Sound Travels In A Water Of Depth 300m,is 216km/h.Calculate The Time Taken By The Sound At That Depth.

2 answers

I would personally 516 since I added them together
d = V*t = 2*0.3 km = 0.6 km
216 * t = 0.6
t = (0.6/216) h.
t = (0.6/216)h * 3600s./h = 100 s.

Note: The sound travels 600m(0.6km).
