One car travels due east at 40 km per hour and a second car travels due north at 40 km per hour Are their velocities equal?

Relative to the Earth, yes.
And actually, neverminding the Earth's rotation, their velocities are still the same. The velocity of the Earth around the Sun, the Sun around the Milky Way and the Milky Way streaking out from a primordial universal "center" make the Earth's rotation - and indeed, the car's personal velocities, irrelevent.
One could be going 100 kph and the other be dead on the road, and in a cosmic sense their velocities are identical. Only the energy each is expending differs in that scenario. Remember, running up and down the aisle of an airplane going 700 mph doesn't actually change your velocity. Just makes you tired!

One car travels due to east at 40km per h and a second car travels north at 40km per h are their velocities equal?
No. "Velocity" includes a magnitude and a direction. If any of the two are different, then the velocities are also different.
If a car is traveling north at 100 kilometers per hour and another car is traveling in the opposite direction at the same speed Are their velocities the same?
No. Velocity includes a directional component. If the two were of the same mass and collided head-on, their velocities (being in the reverse directions) would cancel out.
how fast is the x 15?
The north American x-15 travels at mach 6.72
A boat travels due east for a distance of 15 miles. It then travels due north for distace of 20 miles. How many miles is the boat from it's starting point?
25 miles.
A boat travels due East for a distance of 15miles it then travels due North for a distance of 20miles at which point it drops anchor how many miles is the boat from its statring point?
25 miles

One airplane travels due to north 300kmh while the another travels due to south at 300kmh. Are their velocities the same?
no it is not, velocity includes speed and direction and while the speeds are the same the direction is not
If One car goes east a km second car goes north a km are their velocities the same?
yes of course!
Calculate the resultant of the pair of velocities 100 km north and 75 km south?
100 km and 75 km are displacements, NOT velocities. The resultant displacement is 25 km north,
What is the average velocity of an object that travels 6 meters north in 2 seconds and then travels 3 meters east in 1 second?
3.00 m/s
Can two object's have same speed but different velocity?
=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.
What are examples of velocity?
Take a train going west at 100 miles per hour and another train going south at the same speed. Their velocities are different because velocity is a vector quantity that gives both speed and direction. Since they are going in different directions they have different velocities.
Does Amtrak have train that travels to North Pole?
No
How far does an object travel if its velocity is 25.5 meters per second north and it travels 85 seconds?
Distance = Velocity*Time = 25.5*85 metres = 2167.5 metres.
What is the only river that travels south to north?
The Nile.
Where does The Polar Express take children?
To the north pole
Is 300kmh north the same velocity as 300kmh south?
No. Velocity is described as a speed in a certain direction. Since they are in different directions, they are different velocities.
