MathPhys

Explanation:

Speed has only magnitude.

Velocity has magnitude and direction.

"A bike goes 25 m/s toward  main street."

This includes a direction, so it is velocity (V).

"A person walks 4 mph."

This has only magnitude, so it is speed (S).

"A plane flies 200 m/s."

This has only magnitude, so it is speed (S).

"A bird flies 100 mph due south."

This includes a direction, so it is velocity (V).

Options B and D shows the velocity. While the option A and C represents the speed.

What is speed ?

Speed is defined as the rate of change of the distance or the height attained. It is a time-based quantity. It is denoted by u for the initial speed while v for the final speed. Its SI unit is m/sec.

Velocity is a vector quantity, it needed direction as well as magnitude to define.While the speed is a scalar quantity.

A person walks 4 mph and a plane flies 200 m/s represents the speed.

A plane flies 200 m/s, A bird flies 100 mph due south, represent velocity.

Hence, options B and D shows the velocity. While the option A and C represents the speed.
