Is speed per hour same as average speed?
No. if you are accelerating from rest, for example, and reach 80 mph starting from 0, your average velocity is 40 mph, but your speed is 80 mph at the end. Generally we speak of average speed, so if it takes one hour to go 60 miles your average speed is 60 mph, even though you may have slowed and then gone faster at certain times.
Is the total distance divided by the total time of a trip?
miles per hour * * * * * Only in some parts of the world which still cling to Imperial measures. The question does not specify any units of time and the answer is "average speed.".
Explain how to calculate average speed?
Average speed = d/t (distance covered in some period of time) divided by (the length of time to cover it)
What are some units you can calculate speed?
mph,kph,grams not grams. Grams is weight. MPH, KMPH
What is a car's speed in kilometers per hour?
The answer depends on how fast it is moving - in some units! Unless it is stopped in which case its speed is 0 km per hour!
I have some physics homework concerning braking force and I am having some trouble with it. How do you calculate the average braking force?
The average braking force can be calculated by dividing the change in momentum by the time taken to come to a stop. This can be expressed as (final speed - initial speed) / time. Remember to convert the speed into appropriate units before performing the calculation.

How do you find the average speed of some thing?
Average speed is distance traveled divided by time taken.
Why is light measured in distance and not in time?
-- The distance that light travels in some amount of time is expressed in units of distance. -- The time that it takes light to cover some amount of distance is expressed in units of time. -- The speed of light is expressed in units of speed . . . distance/time
What are the physical quantities and units included in determining speed?
-- The physical quantities involved in speed are distance and time. -- Some popular units of distance include the mile, foot, kilometer, smoot, and parsec. -- Some popular units of time include the second, month, week, fortnight, and year.
Name three common measurements that are expressed as a ratio of two units?
There are many different units require a ratio, some more common units are: distance per unit speed ie m.s-1 (metres per second) molecular weight ie. g.mol-1 (grams per mole) density ie g.ml-1 (grams per ml)
What is the average speed of a gun?
No such thing as an average speed- varies greatly by caliber. I have some firearms that shoot at 830 FPS, and some that shoot at 4000 FPS.
How fast is an average car speed driving on the highway?
Generally, the average car speed is whatever the speed limit is. While some go over and under, others stay right on the speed limit, making it the average.
What is an objects average speed?
An object's average speed is(the distance it traveled during some time)/(the time it took to cover the distance).
What is the calculations for average speed?
Average speed = (distance traveled during some time) divided by (length of time to travel that distance)
What is the average speed on the Internet in Mbps?
Depends on the companie you have your internet from...there is no average speed as some companies have high speed like fiber optic and some still have slow internet like dial up and satelite
What is SI system of units?
The SI system of units is the international system of measurements. It is also known as the "metric system", although technically there are different (but similar) metric systems. The SI system is used in most countries in the world; both scientists and common people generally use SI units such as meter, kilogram, second, square meter, etc.; some common exceptions to this are units of time (the official unit is the second, but other units are used as well), speed (the official unit is meters/second, but kilometers/hour are quite common), and temperature (the official unit is the Kelvin, but the degree Celsius is more common in a non-scientific context).
