The rate of change is often with respect to time t. suppose that d denotes the displacement of a particle, at time t, then you can find the speed with this formula:
d=rt, then to solve for r we divide both sides by t and have d/t=r
In mathematics, it is useful to distinguish between velocity and speed. First, when considering motion of a particle in a straight line, specify a positive direction so that it is a directed line. Then the velocity of the particle is positive if it is moving in a positive direction and negative if it is moving in a negative direction. The speed of the particle is the absolute value of its velocity. In more advanced work, when the velocity is a vector v, the speed is the magnitude |v| of the velocity.

you call it algebra because it has an unknown number which you have to solve for
to be able to solve problems is the main purpose of studying algebra... :)

Linear Algebra is a branch of mathematics that enables you to solve many linear equations at the same time. For example, if you had 15 lines (linear equations) and wanted to know if there was a point where they all intersected, you would use Linear Algebra to solve that question. Linear Algebra uses matrices to solve these large systems of equations.
