As this has already been answered I will answer it again. The answer is called "Speed" because there is no direction given. If you were to travel at 45kl/h in a straight line, and then change to a N/W direction, then this would be known as your velocity even though you may still be travelling at 45kl/h.
In physics, work is defined as the energy transferred to or from an object by means of a force acting on the object as it moves through a distance. Mathematically, work is calculated as the product of the force applied to an object and the distance over which the force is exerted in the direction of the force.
The measure of how far an object has moved is called distance. Distance is a scalar quantity that represents the total length of the path traveled by an object.
The force that moves an object over a distance is called work. Work is defined as the application of force over a distance, resulting in the displacement of the object. The amount of work done is equal to the force applied multiplied by the distance moved in the direction of the force.
Work is defined as force acting over a distance. It is a measure of energy transfer that occurs when an object is moved by a force applied to it. Work is calculated as the product of force and distance moved in the direction of the force.
To calculate how far an object has moved, you can multiply the object's speed by the time it has been moving. Distance = Speed x Time. This formula will give you the distance traveled by the object during that time period.
Speed
Moved. Work is defined as a force acting on an object through a distance.
I guess this depends on your definition of power... scientifically power is defined as force times distance divided by time... the faster an object is moved over a given distance the more power that has been used in moving it.
Judge by the distance it has moved in relation to another object.
The speed of an object does not, by definition, have a direction. Speed is defined as the total distance that an object travels divided by the time that it takes the object to travel that distance. A similar concept which does have a direction is velocity. Velocity is defined as the displacement of the object (how far it has moved from its original position and the direction in which it has moved) divided by the time during which it moved. The difference between these two concepts can also be explained in terms of a runner completing a lap around a quarter-mile track. If it takes the runner three minutes to complete the lap, the runner's speed is .25miles/3minutes. The runner's velocity, however, is zero. This is because the runner starts at the same place that they end (because the track is a loop) so that at the end of the 3minutes they are back where they started which makes their displacement zero.

work
Work is applied to an object and the object is moved over a distance in the same direction of the applied force.
