A car travels 500 miles east in 10 hours. What is the velocity of the car?

Answer 1

Velocity : distance (with direction) divided by time

Velocity of car: 500 miles/ 10 hours or 50 miles per hour due east (velocity is in eastward direction.)

If direction (north, south, east, west) had not been specified, then 50 miles per hour would have been a value of the "speed" of the car.

Speed has no specific direction.
