It takes you 1 min to fill your car's fuel tank with 8.8 gallons of gasoline. What is the approximate average velocity of the gasoline leaving the 0.60-in.-diameter nozzle at this pump

v = 119 in/s

Explanation:

Given,

time to fill car's fuel = 1 min = 60 s

Fuel in the tank after 1 min = 8.8 gallons

diameter of pipe = 0.60 in

average velocity of the gasoline = ?

Now,

Discharge(Q)  =

                  =

We know that

Q = Av

v = 119 in/s

Average velocity of gasoline is equal to 119 in/s.

the total distance traveled by the car is

30km + 49km = 79 km .

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
