# The cyclist’s movement is described by the equation x = 120-10t. What is the projected speed of the cyclist?

| The equation of uniform rectilinear motion has the form: X = X0 + Vx * t, where X is the coordinate of the body at time t, X0 is the coordinate of the body at the initial moment of time, Vx is the projection of the speed of motion onto the OX axis, t is the time of motion.

The equation for the movement of the cyclist has the form: X = 120 – 10 * t, we see that the projection of the speed of movement has a value of Vx = – 10.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
