A ship is moving at a speed of 30 kmph. To know the depth of the ocean beneath it, it sends a radiowave which travels at a speed 200 m/s. The ship receives back the signal after it has moved 500 m. What is the depth of the ocean?

Explanation:
A ship is moving at a speed of 30 kmph. To know the depth of the ocean beneath it, it sends a radio wave which travels at a speed 200 m/s. The ship receives back the signal after it has moved 500 m. What is the depth of the ocean?
Ship is moving 30 kmph
Distance travelled = 500 m = 0.5 km
Time = Distance/Speed = 0.5/30 = 1/60 hr = 1min
Radio wave travelled in 1 min = 60 Sec
= 200 * 60
= 12000
=12 km
Radio wave travelled to & Fro
so Depth Of Ocean = 12/2 = 6 km
the depth of the ocean = 6km
