Sure. If the motion is all in a straight line, then the distance and displacement are equal. ==> The Olympic 100-meter sprint is in a straight line. Distance = Displacement = 100 meters. If the direction of motion ever changes, then the distance and displacement are not equal. (I think if the direction of motion ever changes, then the distance has to be greater than the displacement.) ==> In the Indianapolis 500, Distance = 500 miles, Displacement = Zero, because the Starting line and Finish line are in the same place, so the car finishes at the same place he started at.
That's true only if the entire travel from start to finish is in a straight line.
Distance is a function of displacement. You need to define the origininal position and the present position. The difference between them is the displacement, the distance is the measure (using accepted units) of the difference between the two.
Displacement is the direct distance from start to finish (straight line) so we can't determine this from the info given. The speed is 5m/s so after 140s 700m will have been travelled (5m/s x 140s)
To measure speed, you need a stationary starting poing and finish point, you need a timing device and the object being timed.

Displacement in physics can have multiple meanings dependent on the situation. If you are talking about the universal equations of motion or anything moving then displacement means how far something has 'literally' traveled. It differs from distance because if you where to start somewhere and then run around in a circle you would end in the same place and so your distance traveled would be 0. This would make it hard to find out how much energy you have expended because you technically haven't moved anywhere if you only look at distance. This is where displacement comes in, regardless of where you finish your displacement will be the same whether you run a mile in a Circle and finish in the same place or run a mile in a straight line. Now if you are talking about fluids then displacement will mean the amount of water displaced by an object in a fluid. This can be used to calculate the upward thrust of the fluid on the object. Alternatively, you could simply say that displacement is the distance moved in a particular direction and that it is a vector quantity (gives us both magnitude and direction).

a line. starting from one point and going on as long as it needs to go on. or it could go on forever. it needs a start and a finish...
From Finish to Starting Line was created in 2001.
The displacement would be 0 because displacement is the distance between where you start and where you end so if you end in the same place you start, your displacement is 0.
They all finish exactly where they start.

It finishes in December 2012. Then there doing another one in 2013 :). They finish both by 2014 ^_^.
