average speed will be equal?

Answer 1

Explanation:

Average speed is defined as the total distance travelled by the time taken whereas average velocity is defined as the displacement by the time taken. Since speed is a scalar quantity, the average speed is also considered as a scalar quantity while velocity is a vector quantity.

Answer 2

Average speed is defined as the total distance travelled by the time taken whereas average velocity is defined as the displacement by the time taken. Since speed is a scalar quantity, the average speed is also considered as a scalar quantity while velocity is a vector quantity.

If the motion of an object is along a straight line and in the same direction, the magnitude of displacement is equal to the total path length. In that case, the magnitude of the average velocity is equal to the average speed.
