When looking at a distance vs. time graph, it shows how far an object is traveling over a certain amount of time which can be written like this: distance per time or distance/time (distance divided by time) If we then put units in for distance (let's say meters) and time (seconds) we get this: meters/seconds which is the same as the units for speed.
I assume you refer to the formula distance = velocity x time. If an object moves upward, the distance would become the height.
To determine average speed, you need to know what distance the object traveled in meters over how long it took the object to travel that distance in seconds.
Distance = Velocity*Time = 25.5*85 metres = 2167.5 metres.

The change in distance divided by change in time. So say it moved 10 meters in 5 seconds, it would be 2 meters per second.
30 meters subtends 100 seconds of arc.I get a distance of 61,879 meters.
You first need to acquire more data. Since Velocity is equal to Displacement traveled divided by Time (v=s/t) if you know the distance traveled by the object and the time it has taken the velocity can be computed. watch those units though. if your measuring in meters and timing in seconds your velocity will be in meters/second so this needs to be converted if you are looking for miles or kilometers/hour
The general formula for calculating speed or velocity is given by :- v = s / t [ s divided by t] where v : velocity s : displacement/distance t : time s (displacement) is actually change in the distance, but it can be generalized as just distance traveled. units include : meter, kilometer, miles and other sub types(centimeter, inch) t is the time taken for the object to move the above mentioned distance. units : seconds, hours and other related measures of time. eg : if an object was moved by 15 meters in 3 seconds, its velocity v is given by: v = 15/3 = 5 meters/second or m/s
velocity is distance traveled per unit of time. If you multiply it by time traveled you get distance traveled.For example if you travel 10 meters in one second (velocity) for 20 seconds (time) you travel 10 x 20 = 200 meters
Velocity equal distance divided by time. For example, an object that traveled 5 metes in 10 seconds had a velocity of 5/10 meters per second which is .5 meters per second. Velocity is speed in a direction. Sometimes a navigate or positive number is sufficient as the direction. Other times you will need to be more specific, such as .5 meters per second East or 1.3 meters per second 30 degrees East of North.
Speed = (distance traveled) divided by (time to cover the distance) Speed = (50 meters) / (2 seconds) Speed = 50 meters per 2 seconds Speed = 25 meters per second
The speed of the the object is 20/5 = 4 metres per second.In order to answer the question in terms of velocity, it is necessary to know the direction of motion because velocity is a vector.
If an object moves 50 meters in 5 seconds, its average speed is 50/5 = 10 meters per second.
