If you would like to know how much water did Elena drink each practice if she drank the same amount each time, you can calculate this using the following steps: 5 bottles of water ... 7 practices
x bottles of water = ? ... 1 practice

5 * 1 = 7 * x
5 = 7 * x /7
x = 5/7 bottle of water

The correct result would be 5/7 bottle of water.

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
