a car travels 50 kilometers West and 10 minutes. after reaching the destination the car troubles back to the starting point, again taking 5 minutes. What is the average velocity of the car

Answers

Answer 1

Answer: SPEED is

   (distance covered) / (time to cover the distance) .

The car's average SPEED is

      (100 km) / (15min)

=     6-2/3 km per minute.

VELOCITY is

   (distance and direction between start-point and end-point)
divided by
   (time to travel from start-point to end-point).

The car ended up at the starting point, so the distance between
stating-point and end-point is zero.

Velocity = (zero) / (time to travel from start-point to end-point)

    = Zero .
