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.
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.
Certainly not.You get into your car at 8:00 in the morning, and drive 20 miles to your office. Your car stays in the company garage all day while you work. In the evening, you get in your car and drive 20 miles back home, arriving at 6:00 PM, ten hours after you left.Your average speed for the 40 miles in 10 hours is (40/10) = 4 miles per hour, even though your instantaneous speed was 60 or 70 at some points on the way to and from the office, and zero for most of the day, while the car sat parked in the company garage.
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.
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)
DISTANCE + VELOCITY x TIME So if you travel 90 miles in two hours, 90 = velocity x 2 velocity = 45 miles per hour After 7 hours DISTANCE = 45 x 7 = 315 miles
