On the side of the tracks, the ticket collector is traveling at a speed of 63 mph.
<h3>In physics, what is the speed?</h3>
The rate at which the position of an object changes in any direction. Speed is defined as the relationship between a distance and the time it takes to travel that distance. Speed is a scalar quantity because it only has a direction and no magnitude.
The speed of an object can be determined by calculating the distance it covers in a given amount of time. For instance, if a car travels 70 miles in an hour, it is doing so at a speed of 70 miles per hour.
Vt,g = Vt,T + `VT, g
Vt,T = -2mph VT, g = 65mph
Vt,g = -2 mph + 65mph = 63 mph.
