It depends how the sound travels and the conditions, The speed of sound in dry air, 20°C is 323 m/s
If the boat's velocity is 18m/sec relative to the water in the river and not the shore, it would need to be added the river speed of 2.5m/sec to get a total of 20.5m/sec. The 20.5m/sec would then be the total velocity of the boat relative to the shore. From personal experience, I know that when one runs with the tide, one is adding the tide flow speed to one's boat speed (what it would be in neutral waters) to get a sometimes much faster speed.
Answer:
Its angular speed is 0.105 rad /s. The minute hand of a clock takes 60 minutes = 60 x 60 seconds to complete one rotation.
Hope this Helps!!
Have a nice day :)

Answer:
Well..
Explanation:
That's impossible. I know because I once weighed 11.1 kN, and I was temporarily immobile. It's probably the same for a car, and therefore it can not be "traveling" anywhere at all.. unless you put the car on an airplane or a boat or something.
