The kinematics we can find the time to cross the Atlantic is 67 days.
The kinematics studies the movement of the body making relationships between the position, the speed and the acceleration of the same.
The average velocity is defined as the relation between the displacement between the time of the interval
v =
Δt =
Where v is the velocity, x the displacement t time
In this case they indicate the displacement is Δx = 3000 mi and the speed is v = 50 m / min
The system of units allow data to be exchanged with precision and safety, for this there is currently the international system of measurements (SI), where the unit of length is the meter and the unit of time is the second, let's reduce the magnitudes given to these units.
Δx = 3000 mi ( ) = 4.828 10⁶ m
v = 50 m / min ( ) = 0.833 m / s
Now we can calculate the time to cross the Atlantic
Δt = 4.828 10⁶ / 0.833
Δt = 5.796 10⁶ s
Let's reduce to days
Δt = 5.796 10⁶ s ( ) ( )
Δt = 67 days
In conclusion using kinematics we can find the result of the time to cross the Atlantic is 67 days.

<u>The Differential of Multivariable Functions</u>
Given a multivariable function V(r,h), the total differential of V is computed by
The volume of a cylinder of radius r and height h is
Let's compute the partial derivatives
The total differential is
The differential dr is approximated to and the differential dh is approximated to . We can see the increment of radius is the thick of the metal in the sides, and the increment of the height is the thick of the metal in the top and bottom. Thus dr=0.05 cm, dr=0.2 cm
