If we know the distance something has moved, and the time it took to move there, we can calculate average speed by dividing the distance by the time.
If a truck went 60 miles in 2 hours, it averaged 60/2 miles per hour, or 30 miles per hour.

How can you find the daily mean?
The mean is the average. The daily mean would be the average of all the measurements made on a particular day.
HOW TO CALCULATE SQFT?
Multiply the length measurement by the width measurement and this will give you the area in SQFT if your measurements of length and width were made in feet.
Is measurements can be exact?
They cannot be because of errors that can be made by the measurer, calibration of instruments.
When following the steps of the scientific method when are measurements taken?
the answer is just before the hypothesis is made.
Write the equivalent measurement?
Equivalent measurement are measurements of the same characteristic which are made using two different units. For example, 20 deg C and 68 deg F are equivalent measurements.
Which measurements would not be used to solve for average speed?
There are too many measurements that wouldn't have to be made in order to calculate an average speed. The only measurements that would matter in the most general example are the distance travelled and the time it took.
What did Olaus Roemer discover about light?
Olaus Roemer discovered the finite speed of light in the late 17th century. He observed that the time it took for light to travel from Jupiter to Earth varied as the distance between the two planets changed, leading him to calculate a rough estimate of the speed of light. This discovery laid the foundation for later, more precise measurements of the speed of light.

How should measurements be made when gathering data?
measurements should be made precisely to ensure accuracy (:
How do you calculate net words per minute?
Net words per minute is determined by measuring a typist's average gross speed in words per minute over a ten-minute period and subtracting the number of errors made during that period.
How are average speed and instantaneous different?
You might go at 50 mph for a while, then slow to 20 mph. Your instantaneous speed would be one of these two, depending on when you made the measurement. But your average speed over the distance would be somehwere between 50 and 20, depending on how long you went at each speed.
What are measurements made in?
Measurements are made in units. The specific units that you would use depend upon what it is that you wish to measure. Practically anything can be measured.
Measurements made by hand are more accurate than those made by machine?
The measurements are almost always correct when made by machines. An example would be a calculator.
In what month were the measurements made for sea ice in the year 2008?
Measurements are made every day. The Arctic sea ice minimum occurs in September.
How are metric measurements made?
They are made using appropriate tools or instruments.
What do you understand by term physical quantities?
Basically, anything that can be measured (or calculated on the basis of other measurements) in the world around us. All sorts of measurements can be made, for example you can measure or calculate an object's length, width, mass, weight, density, you can measure an electric current, a voltage, etc. - all of these are physical quantities.
