299,792.458 km/sec in vacuum
Speed of light c = 299792458 m/s × 1 km/1000 m = 299792.458 km/s. Speed of light c = 299792.458 km/s × 3600 s/ 1 hr = 1079252848.8 km/hr.
An airplane travels 80 km in 10 minutes and then flies 100km in 20 minutes the average speed of the plane is? 80 km in 10 minutes = 8 km/min 100km in 20 minutes = 5 km/min Average speed = total distance traveled ÷ total time Average speed = 180 km ÷ 30 min = 6 km/minute Notice the average speed is closer to 5 km/min, because the plane spends twice as much time traveling at the slower speed.
Sound . . . 0.34 km/second Light . . . . 300,000 km/second
This is an average speed of 42.54 km/h
To drive 400 km, you would need to use 40 litres of petrol. This is calculated by dividing the total distance (400 km) by the fuel efficiency of your car (10 km/litre).
it is said to be 250 km/h
The cruising air speed (most fuel efficient speed) is approx.Mach0,82 (871 km/u).The top speed, of the Airbus A330 isMach 0,86 (913 km/u).
10 / 14 x 100 ≈ 71%
It depends on the fuel efficiency of your vehicle which, in turn, depends on its condition, your driving style and road conditions.
I own a 2000 VW Jetta VR6 and I have about 35-40 miles left on mine. This is how to calculate the number for your car. First, you have to calculate the average kilometers per liter fuel efficiency. You can do this by filling up the tank (do not top off) and resetting the tripmeter. Then drive regularly for several hundred km. Then refill your tank and note how many liters you had to add. Then divide the number of km driven by the number of liters, giving you the km/l fuel efficiency. HINT: you can do this multiple times to increase accuracy and to notice if you have a drop in fuel efficiency, which may be a sign of something wrong with your car. Once you have the fuel efficiency calculated, you drive your car, after filling up the tank, until the fuel light comes on. Then immediately fill the tank to capacity (once again, do not top off). Subtract the amount you had to fill up from the tank capacity (documented in the user manual and I believe inside the door of the fuel cap). This gives you the reserve fuel in your tank when the light comes on. In my car it is about 1.5 gallons. Finally, take that number, the reserve fuel capacity, and multiply it by the fuel efficiencey in km/l and this will give you the number of km left when the fuel light comes on.
That's not a speed, that's a distance. For a speed, you have to specify a distance, divided by a time, for example "km / hour" or "km / second".That's not a speed, that's a distance.

Speed is NOT measured in km but km PER HOUR. The average speed was 88.88 (repeating) km per hour.
Average speed is 4 km/h, maximum speed is about 8 km/h
Speed = Distance/Time Speed = 500/7 = 71.42857143 km per hour or 71 km/hour
It is 4,333 km from Perth to Brisbane. About 47 hours of driving. If you're asking how much fuel it takes to get there, that depends on the efficiency of the car you're driving. Cheers!
The speed is 1 km/second.
