Is km s a vector quantity?
km/s can be either a vector or a scalar quantity. It is a unit of speed, which is scalar, but if this speed is in a specific direction, thereby becoming velocity, it is vector.
What is velocity how is it different from speed?
In common language, the terms are used interchangeably. But in physics, speed is a scalar; velocity is a vector. That is, a speed is just a number (and a unit) - for example, 50 kilometers/hour. But when it is important to distinguish a direction, you talk about a velocity. For example, "50 kilometer/hour to the north". Velocity is a speed AND a direction. "50 km/hour north" and "50 km/hour east" are the same speed but different velocity.
Are speed and distance a pair of vector quantities?
Speed and distance are examples of scalar quantities, meaning they only have magnitude. Velocity and displacement are vector quantities, meaning they have both magnitude and direction.Examples of scalar quantities:speed (s) - 10 m/s or 36 km/hdistance (d) - 100 m or 0.1 kmExamples of vector quantities:velocity (v) - 10 m/s [E] or 36 km/h [E]displacement (Δd) - 100 m [E] or 0.1 km [E]The value in square brackets (for vector quantities) indicate direction and include, but not limited to:[S], [N], [E], [W], [45°], [45° E of S], [45° S of E], [forward], [backward] [up/↑], [down/↓], etc...
How fast is a car that covers km in 2 Min's?
30 kilometers per hour.
Does velocity inculde both distance and direction?
Velocity is one of the set of terms categorized under two separate terms. These are scalars and vectors. Scalars are variables containing only one value, for example, speed.40 km/h is a scalar, seen as it has a singular value 40 kilometers per hour. A vector, on the other hand, is comprised of two values, i.e. magnitude and direction. Using the previous example, 40 km/h south, represents a vector. Knowing this we can categorize velocity. Velocity is by definition the rate of change and is a vector quantity. In order to qualify as velocity, speed and direction must be accounted for. In conclusion, velocity includes *magnitude* and *direction*.

km/s can be either a vector or a scalar quantity. It is a unit of speed, which is scalar, but if this speed is in a specific direction, thereby becoming velocity, it is vector.
What two pieces of information do vectors tell us?
A vector includes information about a magnitude, and a direction. For example, a velocity of "30 km/hour, towards the north-west".A vector includes information about a magnitude, and a direction. For example, a velocity of "30 km/hour, towards the north-west".A vector includes information about a magnitude, and a direction.

What is the average speed of a car that travels 30 km in ½ hour?
60 km an hour
How long does it take a car to travel 30 km at 60km per hour?
Time = Distance/Speed = 30 km/60km per hour = 1/2 hour or 30 minutes
What are some examples of scalar and vector quantities?
Scalar QuantitiesMost of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time (minutes, days, hours, etc.) represent an amount of time only and tell nothing of direction. Additional examples of scalar quantities are density, mass, and energy.Vector QuantitiesA vectorquantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. Magnitude, or "size" of a vector, is also referred to as the vector's "displacement." It can be thought of as the scalar portion of the vector and is represented by the length of the vector. By definition, a vector has both magnitude and direction. Direction indicates how the vector is oriented relative to some reference axis, as shown in Figure 1. Using north/south and east/west reference axes, vector "A" is oriented in the NE quadrant with a direction of 45 north of the o EW axis. G iving direction to scalar "A" makes it a vector. The length of "A" is representative of its magnitude or displacement.Another AnswerA scalar quantity refers only to the magnitude of the quantity and answers the question how much. Ex. height, weight, volume, and the like. 2 lbs of sugar is scalar, 4 m long is scalarA vector quantity refers to both magnitude and direction and answers how much and where is it going, (in that sense)Ex. forces, velocity. 200 km/hr at N30degE is a vector, the force required to push a drum up or down a ramp is a vector, the force exerted by the cue stick in billiards is a vector a scalar is a number, like a distance... like the moon is 300.000km away from earth.a vector is a number AND a direction. It's like "moving east at 100km/h"while "moving at 100km/h" alone is a scalar.The idea is that a scalar has only ONE dimension, while a vector has several.

What distance will be traveled if your are going 120 km per hour for 30 minutes?
30 min = half an hour (60/2) so half of 120 km = 60 km
In km per hour find 2.4 km in 30 mins?
4.8 km/h
What is a scalar measurement?
A scalar measurement is one that requires only one number. For example, my mass is 82 kg. BUT some measurements require more than one number to specify. For example, a force on me has both a magnitude and a direction. Such things are called "vectors." Speed is a scalar quantity. I am going 35 km/hr, but velocity is a vector, which requires a magnitude, which is the speed, AND a direction. So my speed is 35 km/hr, but my velocity is 35 km/hr east.
