The speed of an object at rest is 0 (zero).
It is not moving.

If you stand next to an object at rest and measure the speed it will be 0. But, If another guy were in space looking at the earth and he can see the object...the earth (along with the object) would be whiping past him at 1000mph. To that guy in space the speed is huge...to you the speed is 0. The point is the speed is all realative to something else.

Speed is relative. If you and the object are at the same place and object is at rest it means object speed is zero. If you are another planet and earth is rotating then you see object also moving with the same speed of the earth.

Speed of an object at rest compared to its sourrounding is zero but speed of an object compared to solar system is as same as the speed of earth.Because object is on the earth and earth is moving.

There is no speed when an object is as rest because there is no displacement of the object

You at first have to know the meaning of velocity(or "speed" as you say)...
it means "Measuring the rate of change of a body WITH RESPECT TO A FRAME OF REFERENCE".
That means if your object is at rest with respect to a frame of reference that doesn't necessarily mean that the body won't be moving be moving with respect to another frame of reference.
for example,when you are moving inside a train,you are at rest w.r.t. the other travellers sitting inside the train,but you are not at rest if you shift your frame of reference to a tree outside the train.
if you know all these and think these are crap,then read below:
If you say a body is at rest on earth,then consider these:
>the earth is rotating(say the linear speed of that point is 266.67 km/hr )
>the earth is revolving around the sun at a speed of some thousands of km per hour...
>the solar system is revolving at some millions of km/hr
>the whole milky way is going at some velocity near to the elocity of light
>sincerely, after that we don't have a clearer idea what is moving where...!!!
then vectorially addup everything and you get your answer.
>>>or you may research to find out a way to measure the speed of the body with respect to "Ether" (which now-a-days is crapped by the scientists when the found no way to detect even that ! )
huh! don't you think i can be a good writer?
my fingers are tired of typing...
may be some day i can give you a clearer picture!
bye...

when and object is at rest it does not travel,so the speed is 0

An object at rest does not have a speed!
Though you can attribute it to gravitational rotation, and take that speed, which would be the rotation speed of the earth.

at rest, speed = 0

it depends on your inertial frame. If the measured frame and object both moving with constant speed v relative to each other, then the speed of rest object relative to observer moving with the frame is v.
