Question

if the depth of sea is 3,42,000 km and it takes 14 seconds for the transmission to reach the ship . find speed of sound .​

Answer 1

Answer:

speed = distance / time

SPEED = 342000000 METRES / 14 SEC

           =24.4285714286 X 1000000

speed of sound =24428571.4286 M /S

HOPE..IT..HELPS..!!

Answer 2

Answer:342000/7 km/sec

342000×3600/7 km/hr

And 342000×3600×5/18×7

Ab bhagwan ne calculator nikala hain toh uska upyog kar dena

Explanation:

Total time=time for sound to reach ground+time for sound to come back=14 ..and

Time for sound to go = time for sound to come = 14/2=7secs

Now dist =342000

Time = 7 secs=

3600 secs =1hr

7secs =7/3600 hrs

Dist/time=speed=342000×3600/7 (km/hr)
