What is the speed of a hockey puck moves 45 meters in 5 seconds?
Speed in physics is called velocity what you are looking for when you are talking about speed/velocity you are looking for an answer with the units being "distance/time" such as "miles/hour" in this case you are using the distance measurement of meters and the time unit of seconds therefore you want an answer in "meters/second." Ergo, you divide the unit of distance by time so it would be "45 meters/5 seconds" which would simplify to "9 meters/second" where the symbol "/" can be pronounce as "per" so it could be written "9 meters per second" I hope you did just get the answer, but rather some of the thought process of the issue.

If the 1st 2nd and 3rd dimensions can be measured in distance units can the 4th dimension or time be measured using the same units?
No - because time is measured in seconds, not linear distance.
Why do people need to know how to convert units?
Different units are often used to measure the same type of thing (for instance, length). Sometimes you want to convert to another unit, just to visualize the amount - for example, if you are accustomed to seeing lengths expressed in meters, you may have trouble understanding feet. Or perhaps the other way round. Also, when using formulae, units need to be compatible. As an example, in the formula commonly used for speed problems: distance = speed x time distance might be in meters, time in seconds, in which case speed must be in meters per second. If one of the units is incompatible, it must be converted first.
how to convert radius into meters?
That depends on the units the radius is measured in. Radius is a distance and can be measured using any unit of length.
What is the unit that time is measured by?
In the International System of Units (SI Units), time is measured in seconds.

3 kinds of measurement?
Length: Measured using units such as meters or inches to determine the extent of an object from one point to another. Weight: Measured using units such as kilograms or pounds to determine the mass of an object or person. Time: Measured using units such as seconds, minutes, or hours to quantify the duration of an event or activity.
What is a system of units used by scientists that is based on units of ten?
The metric system is a system of units used by scientists that is based on units of ten. It includes units such as meters, kilograms, and seconds. This system makes it easy to convert between different units by using prefixes like kilo, centi, and milli.

What unit can not be used to express volume?
Units that cannot be used to express volume include units of time (such as seconds or hours) and units of angles (such as degrees or radians). Volume is typically measured using cubic units like cubic meters or cubic inches.
How do you solve 2.2 meters equals how many mph?
You can't convert that. One is a distance measurement, the other is a speed measurement. If it is a speed problem, use the formula distance = speed x time. In this case, you need to know how long it takes to advance those 2.2 meters. You also need to convert all the units to compatible units first - for example, using meters for distance, seconds for time, and meters/second for speed.
Show that the units N and kg can be written using only units of meters and seconds Is this a unit of mass acceleration or force?
After diligently unraveling the question, I think it asks us to show something that's not true. 'N' ... the 'newton' ... is the SI unit of force. 1 newton = 1 kilogram-meter/second2 . It can't be defined with a unit of mass. 'kg' ... the 'kilogram' ... is a basic SI unit in itself. It can't be written in units of anything but mass. It seems that there is some sort of truthful undercurrent flowing through this question which, because of a word or two carelessly mis-copied, is not quite visible from the surface.
What are the units for measuring area?
You can use any units of distance you want. If you measure the sides of a rectangle using feet, the area will be in square feet (ft²) If you measure using meters the area will be in square meters (m²) Here is an example of the math Area = length x width = 3 meters x 4 meters = 3x4 meters x meters = 12 square meters = 12 meters squared = 12 m²
Why are the standardized units of measure important to scientists?
The base SI units: length (meters), mass (kilogram), time (seconds), luminosity (candella), current (amperes), amount (moles), temperature (Kelvin)
How long is 25000 hours?
It depends on what units you're using. It's 1,500,000 minutes or 90,000,000 seconds.
Why you have second square in the unit of acceleration?
The unit of acceleration is m/s^2 because it represents the rate of change of velocity with respect to time. The square in the unit indicates that the quantity is being squared, which is necessary in this case to calculate acceleration correctly.
