How do you calculate distance in hours?
You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
How do you work out fuel consumption per km?
Calculating a vehicle’s fuel consumption is not difficult. Simply note down the distance travelled since the last top-up and then take a note of how much fuel it consumed to travel that distance, then divide the litres used by the kilometres travelled and multiply by 100 to calculate consumption in litres/100km.
How do you calculate speed using distance and time?
The formula can be rearranged in three ways:
- speed = distance ÷ time.
- distance = speed × time.
- time = distance ÷ speed.
What is the fastest possible speed in the universe?
300,000 kilometers per second
Why is constant speed?
The Direction of the Velocity Vector Objects moving in uniform circular motion will have a constant speed. The direction of the velocity vector is directed in the same direction that the object moves. Since an object is moving in a circle, its direction is continuously changing.
Is constant speed and uniform speed same?
The velocity is said to be constant if the body moves along a straight line without changing its direction. The velocity is said to be uniform if the body covers an equal distance in an equal interval of time. The velocity is said to be constant if the body moves along a straight line without changing its direction.
Does constant acceleration means uniform velocity?
Constant velocity is the velocity whose direction as well as magnitude remains constant. Uniform velocity is the velocity whose magnitude(only) increases with equal intervals of time….Thank you.

Does uniform acceleration means uniform velocity?
Ex: A car moving in a speed of 60kmph for a specific period of time is said to be in uniform velocity. If the final and initial acceleration is same then the body is said to be in uniform acceleration.
Why uniform velocity has no acceleration?
If the velocity is uniform, it means that it is not changing hence there is no acceleration. Acceleration is rate of change of velocity. When velocity is uniform there is no change with reference to time, therefore zero acceleration.
What is the difference between non uniform velocity and acceleration?
Just like how velocity quantifies how the displacement is changing with time, acceleration quantifies how the velocity is changing with time. Graphically, non-uniform velocity is just the curve in velocity-time graph. And acceleration is the slope at (around) each point in the curve.
What is the formula of uniform velocity?
The condition in which a body covers equal distance in an equal interval of the time is known to be uniform velocity. In equation( d=v t ) v is the average velocity of a body during time t.
What is the SI unit of velocity?
Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1).
