Average speed = Total Distance/Total Time = (15+25)/2 = 40/2 = 20 miles per hour.
Velocity (due North) = Total NET distance North/Total Time = (15-25)/2 = -10/2
= -5 miles per hour
or, velocity due South = 5 miles per hour.

A car travels 100 miles east in 2 hours and 30 miles north in one hour. What is the average speed of the car?
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
What is the velocity of a car that traveled a total amount of 75 kilometers north in 1.5 hours?
50km/hour North.
Is speed equal to velocity?
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
What is 20 miles per hour north an example of?
A velocity vector includes both speed and direction.
Which is 20 miles per hour north an example of?
A vector. This is because the quantity given has a magnitude (20mph) and a direction (North). It is also an example of a velocity.
Find the velocity of a truck that travels 75 miles north in 2.5 hours?
Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
A car travels 100 miles east in 2 hours and 30 miles north in one hour. What is the average speed of the car?
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
What is the difference between speed and velocity is that velocity?
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.
Can speed equal velocity?
Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.
What is the velocity of an car that travels 50 miles north turns around and travels 50 miles south in 5 hours Question 6 options 0 2 mph south 5 mph south 25 mph north?
Velocity is speed and direction. The velocity would be zero because the 50 miles N cancel the 50 miles S. The speed is 100 mi/5 h = 20 mph.
What is the velocity of a car that travels 260 miles in 4 hours driving to the northeast?
Divide the distance by the time to get the speed. The direction, of course, is north-east.
The difference between speed and velocity is that velocity include?
Speed is a scalar and velocity is a vector. A scalar only has magnitude while a vector has magnitude and direction. Example: If you are traveling north at 65 miles an hour your speed is 65 miles an hour, your velocity is 65 miles an hour north. It gets a little more complicated. Speed = distance (a scalar)/time Velocity = Displacement (vector)/time Example: If you run 5 miles in an hour left and then 5 miles in a hour right your speed is 10 miles/2 hours = 5 miles an hour. However, since you end up in the same exact location as where you started your displacement is zero making your velocity zero as well. Think of it this way; since velocity is a vector it requires a direction if i ended up exactly where I started I have no direction, thus velocity must be zero. One more example to clarify: If you ran 6 miles right and 4 miles left in 2 hours, your speed will be 5 miles an hour (10/2=5) your velocity would be 1 mile an hour to the right, since displacement is 2 miles to the right (6 to right - 4 to left = 2 to right) and the time is 2 hours displacement/time = velocity; 2 to the right/2 = 1 mile to the right per hour.
What is a example of a value for velocity?
30 miles per hour north
What is the velocity of a car that traveled a total of 100kilometers North in 2 hours?
The average velocity during that period of time is 100 kilometers per 2 hours north. It may also be stated as 50 kilometers per hour north.
Is six miles per hour per second north an example of velocity?
We're not completely sure what you mean by "per hour per second". Going just by what we see in the question, it's an acceleration, not a velocity. "Six miles per hour north" would be a velocity.
How can you differentiate velocity from speed?
If no direction is mentioned, then you have a speed. Example: "30 miles per hour". If the direction is mentioned, then you have a velocity. Example: "30 miles per hour north".
How can the velocity of an object change if the speed doesn't?
Easy answer: velocity is defined as speed in a specific direction. So, if a car is traveling at a velocity of due west, 60 miles per hour, then turns onto a road going north, the velocity has changed to due north, 60 miles per hour. But the speed has stayed the same.
