A vehicle travels 2345 m in 315 seconds toward the evening sun. What is its velcity
Velocity is the derivative of position.
\(v={dx\over{dt}}\)
In a linear and finite application \(v={\Delta x\over{\Delta t}}\)
Speed is then simply distance covered, divided by the time it took to cover the distance.
This gives you a value of the average speed.
In units: meters divided by seconds = m/s which is really only a factor away from km/h or mph (both are units distance per unit time)
2345/315= 7.44 m/s
