At an average speed of 60 kph, in 3 hours the car would have travelled 60 x 3 = 180 kilometers.
speed = distance/ time
=380/3.9 = 97.44 km/h
The answer will depend on whether you took 5.8333333 seconds, hours, days, years. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
You divide the distance traveled by the number of hours it took to travel it. For example, a 500-mile trip completed in 10 hours = 500 / 10 = an average of 50 miles per hour.
Speed is a function of distance and time. For example we refer to 'miles per hour' or 'kilometres per hour' or 'feet per second'' or metres per minute' etc. To determine speed, you need to know the distance travelled and the time it took to travel that distance.
i it just over an hour in light speed but by rocket it took the cassini probe even years to reach Saturn. Pioneer 11 took 6 years
It has to do with the nature of space and time or more accurately, the nature of spacetime. It turns out that both space and time are relative and how much space and time you experience depends on your frame of reference.For example, imagine you were to travel in a spaceship at 99% the speed of light to a distant star that was a 100 trillion kilometers away .Those left at home would see the distance you traveled to be 100 trillion kilometers and would consider the time it took you to be about 10 years.However, you in the spaceship would only measure the distance to the star to be 14 trillion kilometers instead of 100 trillion kilometers and you would think it only took you 1.4 years to travel there instead of 10 years.If you traveled even faster at 99.99% the speed of light you would measure the distance to be 1.4 trillion kilometers instead of 14 and you would think it only took you 0.14 years instead of 1.4.If you traveled even faster at 99.9999% the speed of light you would measure the distance to be 0.14 trillion kilometers instead of 1.4 and you would think it only took you 0.014 years instead of 0.14, and so on.The closer to the speed of light you travel the shorter the distance becomes for you and the less time it takes you.As you can see "space and time becomes less and less" for you in the spaceship relative to us here on the earth.What it comes down to is that different people see space and time differently, depending on the "frame of reference" from which they are looking at things.Note however that it would be impossible for you to travel at exactly the speed of light because it would theoretically take you an infinite amount of energy to get up to that speed. Light can do it because it has no "rest mass".For light when it travels from one point to another at the speed of light, from its point of view, it experiences no passage of time and there is no distance between the two points.
90km divided by 3 hours is 30km per hour
24 kilometers
60 kph, which is derived from taking the 240 kilometers it has travelled total and dividing by the four hours it took to traverse said distance.
200km
Buzz's speed can be calculated by dividing the distance he traveled (150 kilometers) by the time it took him (1.5 hours). Therefore, Buzz's speed is 100 kilometers per hour.
You would take the total distance divided by the total time. 1678 kilometers divided by 3 hours equals 559 and 2 thirds kilometers per hour. or 347.55 miles per hour.
Speed = distance/time km/hr = 90km/3hr 90/3=30 30km/hr
If it averaged 6 kph on the trip back and took 4 hours, the distance of one way was 24 kilometers. If the trip there took three hours, 24 kilometers / 3 hours= 8 kph
That depends on what data you have. If you know the distance travelled and the time it took, just divide the total distance by the total time. If distance is in kilometers, and time in hours, then the speed will quite naturally come out in km/hour.

Velocity (or Speed) = Distance ÷ Time The speed for the journey to the fairground = 75 ÷ 1.5 = 50 kilometres per hour.
154 miles / 5.5 hours = 28 miles / hour
