The average speed during that time is 20 km per hour. We can't say anything about
the velocity because you've told us nothing about the direction it traveled.
"Velocity" is NOT just a fancy word for 'speed'. It has a different meaning.
20km\h
It is 20 km per hour, due North.
The average during that period of time is 20 km/hour west .
The average velocity during that time is exactly 556km/3.4hr northeast. The magnitude, expressed in a more familiar unit, is roughly 163.529 km/hr. (rounded)
144/48 = 3 hours
Simply divide the distance by the speed. The answer, in this case, will be in hours.
It is 20 km per hour, due North.
The average during that period of time is 20 km/hour west .
40 ÷ 2 = 20 km/hThe average speed (velocity) is 20 kilometres per hour.
100kmh
The velocity of the car is 32 mph
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
The average velocity during that period of time is 100 kilometers per 2 hours north. It may also be stated as 50 kilometers per hour north.
If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.
Yes, if the car moves in only one direction.
With the information given, it's not possible to calculate what it is now. But during that 90 minutes, its average velocity was 50 kph north.
rms means root mean square, or in a roundabout way the average. Therefore the average velocity or average speed (of a car?)
The average velocity during that time is exactly 556km/3.4hr northeast. The magnitude, expressed in a more familiar unit, is roughly 163.529 km/hr. (rounded)
