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.
The object's average speed during that period of time.
That's 'speed'.
(Not 'velocity'.)
speed = distance/time

Work is the transfer of energy. It is performed when a force causes an object to be displaced causing the object to be moved in the direction of the force. Work = force x distance.
Distance
The distance moved by the object can be calculated by dividing the work done by the force applied. In this case, the distance is 15 meters.
work
Work is done when a force acts on an object as the object moves from one place to another. Work is defined as force times distance.
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 is the transfer of energy. It is performed when a force causes an object to be displaced causing the object to be moved in the direction of the force. Work = force x distance.

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