<h3>step by step instructions:</h3>
Correct option is
D
All are correct
the equation of a given progressive wave is
y=5sin(100πt−0.4πx) ......(i)
The standard equation of a progressive wave is
y=asin(ωt−Kx) ...(ii)
Comparing (i) and (ii), we get
a=5m,ω=100π rad s
−1
,k=o.4πm
−1

Use easy numbers if you get confused on problems like these.
I'm going to use 12 instead of c.
Since you have 12 pieces of candy and 6 friends, each friend would get 2 pieces, because 12/6=2.
Now, substitute c for 12, and you get c/6.
Hope this helps!
