velocity is the distance divided by the time it takes to go that distance.
let velocity equal V
let distance equal D
let time equal T
v = d/t
velocity has units of length per rate
distance has units of length
time has units of rate
the length can have units such as
1) meters, centimeters, millimeters, kilometers
2) feet, inches
3) yards
the time can have units such as
1) seconds, minutes, hours, years
it depends on which system you are using for you units then you will know which units to choose from. the most common is meters per second (m/s)

What happpens to a car moving at a constant speed as it turns a corner?
The car undergoes a change in velocity. It accelerates (and does so at a constant rate - if the rate of turn is constant) in the direction of the turn. The speed is constant, but the direction the car is going changes at each instant in time because it is turning. And because it is changing direction, that means its velocity is changing (because velocity is speed plus a direction vector).
What are all the roots for the equation 3w - 14 - 6 21?
The roots (or solutions) are the numbers that 'w' must be in order to make the equation true.Since the highest power of 'w' in the equation is the first power, there's only one solution.3w - 14 - 6 = 21Combine the -14 and the -6 on the left side:3w - 20 = 21Add 20 to each side:3w = 41Divide each side by 3 :w = 41/3 = 132/3
Two buses depart from Chicago and going to New York and one to San Francisco. Each bus travels at a speed of 30ms. Do these buses have equal velocities explain.?
No the two buses do not have equal velocities because VELOCITY is the SPEED in a given DIRECTION. One would have a velocity of +30m/s because it is traveling in one direction, and the other would have a velocity of -30m/s because it is traveling in the opposite direction.
How does 0 25 50 75 and 1 relate to each other?
This is an arithmetic sequence; or a sequence that is done by addition of constant form of variable. In this case, the variable is x, and x = 25. Proof : 0+25 = 25 25+25=50 50+25= 75 75+25 = 1
What is the similarity between an ordinary chemical equation and a nuclear equation?
A chemical equation puts down on the LHS the chemicals mixed together and on the RHS the results. A nuclear equation puts on the LHS the target element, with an incident particle if relevant, and on the RHS the results. But in a chemical process the constituent elements must balance on each side, whereas with a nuclear change the elements can be converted to other elements.
What does each variable stand for in the equation?
The answer depends on the equation!
What is writing units of each variable in a real life problem?

True or false In a nonlinear equation each variable must only have one solution?
In a nonlinear equation, each variable must only have one solution.
A number multiplied by a variable?
A number, multiplied by a variable is part of an Algebraic equation. A person can find out the value of the variable if they divide each side by the number that is next to the variable. For example, if the equation is 5x = 60, divide each side by 5 and the answer is x = 12.
What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.

Wha is a linear equation?
A linear equation is when each term in the algebraic equation is either a constant or the product has a single variable and a constant.
In a nonlinear equation each variable can have more than one solution?
True
How do you solve the equation 720 equals 2a x 3b x 5c?
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
How do you solve algebra equations?
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)
