What is the relationship between distance, time and speed??

Everyone above assumed a constant speed.  the more general formula is \n\nD = ∫v dt

If initial speed is V0 and the speed after a time t second is V,\n\nAcceleration is change in speed per unit time.\n\nAcceleration a = (V - VO) / t.\n\nThe average speed during this time t is \n\nV (average) = (V + V0) / 2.\n\nNote; if any quantity is changing uniformly, the average is found by adding the initial and final value and dividing the sum by 2.\n\nThe average speed can also be determined by dividing the total distance by total time of travel.\n \nV (average) = S / t.\n\nTherefore S/t = (V + V0) / 2.\n\nS = (V + V0)* t / 2.\n\nFrom a = (V - V0) / t we have V = V0 +at.\n \nTherefore S = {V0 +at + VO} * t /2 \n--------------- = {2 V0 t + at t } /2\n\n-------------- S = V0t + 0.5 a tt

Time is relative.  It doesn't really exist.  Time is effected by the speed of motion, and is not an object.

There will be some relativistic time dilation, even at highway speeds... but nothing you'd ever notice. I figure time dilation effects would be 1 part in 116,640,000,000,000 at 60 mph (100 km/h).

F = d/dt(mv) [the time deravitive of the momentum] = dp/dt  where p is the momentum\n\nWork = Energy = F x distance\n\nPower = Energy/time\n\nPower = (F x distance)/time\n\nPower = [(dp/dt) x distance]/t\n\nremember dp/dt = d/dt(mv) = m dv/dt + v dm/dt

1st way :-\ndistance = speed x time = 55 mph x 3 h = 165 m\n\n2nd way :-\ngiven that d = 55t , so on putting t = 3hrs , we get d = 165 m

Let t be the time, the same time for both then because distance is rate times time the equation is\n\n90t + 80t = 425\n170 t = 425\nso t = 2.5 hours

Speed = Distance/Time\nDistance = Speed x Time\nDistance traversed = 48 x 2.5 = 120 miles\nDistance Remaining - 146 - 120 = 26 miles.

Rabid_Scientist is entirely correct.  Both you and your home see time in the other place as speeding up.  I do have something to add to that though.  If you maintain a constant velocity, it can only be measured relative to some other point of reference, so there is no way to determine which is faster, and consequenty it cannot be determined whose time is actually going faster.  However, if you are accelerating it's a whole different story.  As you speed up to that super fast speed where the time differental starts to be noticable, you will see time on your home planet speed up and they will see your time slow down. (Sorry, I'm not going to try to explain this, I'm not sure I entirely understand it myself).  If you were to go back to your home planet, far more time would have passed for them than for you.  This effect will be greater with greater acceleration and greater speed so in that regard time will pass on your home planet more quickly the faster you go.

just use the formula avg.speed=distance/time\nfor km/hr change time to 2.25 hr\nand for m/sec change distance to 500000m and time to 135*60sec\ndo these ques yourself. in exams you won't have yahoo answers\n:)

velocity is just a term that means "speed" - the distance traveled per time unit \n\nthe "speed of light" is a number - the actual speed (velocity) that light travels, usually reported in meters/second (distance/time)

1) distance is measured in a particular direction. the vector woudl be displacement\n\n2) speed assumes a direction, vector would be velocity\n\n3) power is a unit of energy work\n\n4) force is a vector as you need to say how hard and which way

SPEED=dy/dt=distance/time.its not exactly something you invent.it was an axiom,a basis of understanding.

Time is a measurement of movement through space. The earth rotates around the sun once = one year, the earth completing one spin on it's axis = one day, etc...\n\nFor measuring distances in space we use light years (the time it takes for light to go from point a to b) instead of miles because the distances are so great. Example: If we look at the closest star in the night sky, it's about 4 light years away. That means it's measured by how long that star's light takes to reach our eyes. So we are really looking at how the star looked 4 years ago, not now. If that star exploded 2 years ago, we would still see it for another 2 years and then we see it explode.

speed=distance/time\nso ans=118.5/14 =8.4642km/hr
