The answer is frame of reference
frame of reference gives a pictorial indication of how far and object has moved
Knowing how fast sound travels through water, the time taken for a noise to travel to a target (e.g. a shoal of fish or the sea bottom) and back gives an indication as to how far away the target is. The speed of sound in water is approximately 1500 m/s, so if an echo returns after 2 seconds then the reflecting object is 1500 m away.
speed How fast in which direction is velocity.
Yes, but it takes longer.
To measure smaller object use ruler or measuring tape. Or For long paths use laser distance measurer Or For further long distances use Side road millage stones Or For Still long distances JUST USE google earth :p Hope it helped

Speed gives the information that how fast a certain object is moving and it can be calculated by dividing distance with time in which that distance is covered
yes
Speed
This is an indication you have a bulb burnt out on the side the blinker is blinking real fast.
No. A vertical line on a position-time graph would mean that an object moved a given distance in zero time, in other word that it traveled infinitely fast.

speed How fast in which direction is velocity.
speed How fast in which direction is velocity.
A vector is used to represent direction and magnitude of speed. Velocity is the speed of an object and a specification of its direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. Therefore a vector can be used to represent a velocity. The term "resultant velocity" implies a change in velocity which can be determined using vector analysis.
Yes, but it takes longer.
