An investigator team transmit an ultrasound signal to the sea bed. The signal is received back in 12 second. If the speed of sound in water is 1000 m/s, then the depth of sea is

A

5 km

B

6 km

C

600 m

D

4000 m

Text Solution

Verified by Experts

The correct Answer is:
B
Here, `v =1000"m/s", t =12" s"`
Total distance travelled by sound,
`2d = v xx t`
`d = ( v xx t)/(2) = (1000 xx 12)/( 2) = 6000"m" =6" km"`
Hence, the depth of sea `= d = 6" km"`
