Speed = Distance / Time

Speed = Distance / Time

Speed = Distance / TimeSpeed = 600 km / 2.5 h

Speed = Distance / TimeSpeed = 600 km / 2.5 hSpeed = 240 km/h

Answer: 240 km/h Speed is distance over time.Copyright 2010 Ryan P. Murphy

VVelocity = Distance / Time

VVelocity = Distance / TimeVelocity = 165km / 4 h

VVelocity = Distance / TimeVelocity = 165km / 4 hVelocity = 41.25 km/h/North

Answer: 41.25 km / h / North Velocity is distance over time and direction.
