A car travels 2.5 hours in a northerly direction for

300 km. Determine the car's speed and

velocity. Show all work!

Answer: 120 km/h north.

Explanation: Speed is distance traveled per block of time. As an equation, this is

Speed = distance/time

In your problem, the given distance is 300km, and the time is 2.5 hours.

Plugging into the equation,

Speed = 300km / 2.5 h

Speed = 120 km/h

Velocity is speed and direction.

The velocity would be 120 km/h north.
