Answer:
5000 m equivalent to 5 Km
Explanation:
Average velocity =
so, Displacement =Average velocity × time
We should convert Km/h to m/s so Km/h ⇒  m/s, also convert time to second so, 20min ⇒(20* 60)seconds
 m/s, also convert time to second so, 20min ⇒(20* 60)seconds
Displacement = (15 × ) × (20×60) =5000m OR 5Km
) × (20×60) =5000m OR 5Km
 
        
             
        
        
        
I think the correct answer would be one half the wavelength. Waves would "feel bottom" when the water is at the depth of 0.5 of the wavelength. "Feel bottom" is a term used to describe that the depth of water affects the wave properties. Hope this answers the question.
