Runner A is initially 8.0 mi west of a flagpole and is running with a constant velocity of 5.0 mi/h due east. Runner B is initially 3.0 mi east of the flagpole and is running with a constant velocity of 3.0 mi/h due west. How far are the runners from the flagpole when they meet?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

(mi)
Given: The distance of the runner A from the flagpole is 8.0 mi west
The velocity of runner A is 5.0 mi/h.
The distance of the runner B from the pole is 3.0 mi east
The velocity of runner B is 5.0 mi/h.
To determine: The distance of the runners from the flagpole
Assume the time T at which both the runners meet
The distance covered by runner A is the product of speed and time
The distance covered by runner B is the product of speed and time
The total distance covered by both the runners is
