Cupid fires an arrow that strikes St. Valentine, producing the usual sounds of harp music and bird chirping as
Valentine swoons into a fog of love. If Cupid hears this
telltale sound exactly one second after firing the arrow and
the average speed of the arrow is 40 m/sec, what was the
distance separating them? Take 340 m/sec for the speed of
sound

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
