total distance = 2m + 80m = 82 m total time = 2s + 40s = 42s → average speed = total distance / total time = 82m / 42s = 1 20/21 m/s ≈ 1.95 m/s
In general, we will find the average speed of a moving object by dividing the total distance it travels by the total time elapsed in its travel.We can find the actual speed of the object if it moves with a constant speed during all of its travel. But if the object is something like a bus or train that makes stops along the way, we discover its average speed by dividing the total distance it travels by the total time it took to travel that distance.
Not enough information. You also need to know how much the acceleration is. Once you know that, calculate the final speed, then calculate the average speed as (initial speed + final speed) / 2, and multiply that by the time to get the distance.
Distance is the length of anything or the distance between any two points. In standard units, it would be measured in inches, feet, yards, or miles. In SI unites, it would be measured in mm, cm, m, or km. In Astronomy, one might also use AU (distance from earth to sun), or lightyears (distance light travels in a year). Velocity/Distance calculates are common in mathematics, but perhaps only moderately applicable in the real world as speeds often vary during a trip. However, people do frequently try to estimate the expected duration of a trip.

Energy travels from one place to another during a wave motion. Particles in the medium may also oscillate in place as the wave passes through, but they do not permanently move from one location to another.
total distance = 2m + 80m = 82 m total time = 2s + 40s = 42s → average speed = total distance / total time = 82m / 42s = 1 20/21 m/s ≈ 1.95 m/s
No, light refraction does not increase during distance vision. Light refraction occurs when light travels from one medium to another of different optical density, causing it to change direction. The amount of refraction is determined by the difference in optical density between the two mediums, not by the distance of the object being viewed.
The greatest distance the knot travels from its resting position is called the amplitude. This measures the maximum displacement of the knot from its equilibrium position during its oscillation.
The distance traveled by a wave during a single period is one wavelength. The wavelength represents the distance between two successive points of a wave that are in phase with each other.
Answer: The average speed of the object is 1.95 m/s. Explanation: Distance traveled by an object in the first interval, = 2 m Time is taken in firsts interval = 2 s Distance traveled by an object in the second interval, = 80 mm Time taken in second interval = 40 s The average speed of the object is 1.95 m/s.
Light travels at a slower speed in glass compared to vacuum. The ratio of the speed of light in vacuum to the speed of light in glass is called the refractive index of glass. So, the distance light travels in glass would be the distance it travels in vacuum divided by the refractive index of glass.

During refraction, a wave changes direction due to the change in speed as it travels from one medium to another, causing the wavefronts to bend. This change in direction occurs because the wave changes its propagation speed and hence its angle of incidence with respect to the normal.
What determines the amount of horizontal and vertical distance a basketball player travels while making a slam dunk is momentum. The players weight and velocity combine to carry momentum as he jumps, soars, and lands.
