2 minutes = 120s
S (distance) = v (velocity) x t (time)
S= 3 x 120
S = 360m
So, D is a correct answer
In Medicine, "etiology" means the origin or cause of a disease.
Similar to Hippocrates, modern scientists who study etiology believe that diseases come from natural causes such as bites from infected insects.

Answer:
88.8 m/s= Speed of wave propagation in the required mode.(3 loops)
Explanation:
When there are 3 loops.
the total length = L = 3 λ /2
⇒ λ = 2 L / 3 = 2 ( 1.11 ) / 3 = 0.74 m
Velocity = v = f λ = (120)(0.74) = 88.8 m/s
