velocity = distance/time

velocity = 2345 m/315 sec

velocity = 7.4 m/sec

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
