The parallax method is a way of measuring distances of far-away objects. Astronomers use parallax to measure the distance to stars. Parallax is a measurement of the shift of a nearby object compared to distant objects when observed from two different positions. You can see this effect for yourself. Cover your right eye and look directly at something some distance away, like a tree or house. Hold your hand at arms' length and stick up one finger, and cover the tree with your finger. Now uncover your right eye and cover the left eye, WITHOUT moving your hand. Your finger is no longer covering the tree. The "parallax shift", the distance that your finger appeared to move (relative to the tree in the background) can be used to measure how far away things are. For nearby objects in the solar system - for example, a comet or an asteroid - two observatories can observe the same object at the same time, and measure the "parallax angle" between the comet and a distant star. Knowing how far apart the two observatories are will let you calculate the distance to the comet. For other "nearby" stars, we assume that the stars themselves aren't moving quickly. Take one measurement today, and another measurement exactly six months later. We know the distance between the two observations is 184 million miles (twice the Earth's orbital radius). If our reference star is far enough away, we can use the parallax angle to calculate the nearby star's distance. For VERY distant objects, this doesn't work, for two reasons. 1. The parallax angle is too tiny to be measured accurately 2. We cannot be sure that the reference star in the background is far enough away from the "nearby" star to accurately calculate the distance.

The light travels farther.Sound takes about 10 days to cover the same distance that light travels in 1 second.
(distance the car travels) divided by (time it takes to cover that distance)
A light-second is the distance that light travels in a second, i.e., 300,000 kilometers.
One pounce for a cheetah each time can cover about 20 ft
well i can cover that distance sprinting in 3 seconds
If by "ms" you mean meters per second, then it would run 75 meters in 25 seconds. If by "ms" you mean miles, a cat is not going to cover 3 miles in 25 seconds, but for argument purposes, the distance the cat would run in 25 seconds would be 3 miles.
"Mean" means "average"= (distance covered) divided by (time to cover the distance)= ( 90 / 4.5 ) = 20 feet per second
An object's speed is (distance it travels) divided by (time to cover the distance). The object's mass doesn't matter at all.
The rate that you cover a distance is your speed. Speed is a measure of the distance traveled per unit time. If your units are meters and seconds, then your speed would be in meters/second. To find the speed of something you divide the distance it traveled by the time it took to travel that distance. For example if something traveled 40 meters in 10 seconds its speed would be (40 meters)/(10 seconds) = 4 meters/second
Average speed = (distance covered) divided by (time to cover the distance) = 30/5 = 6 meters per second.Equivalent to 21.6 km per hour.
12 minutes = 720 seconds
Light in a vacuum travels at 300,000 km per second. It will take distance divided by speed time to travel. Or 30 million thousand km divided by 300 thousand km/s = 100 000 seconds. This is 27.8 hours.
