Veronica’s velocity was measured as 4.3 m/s. she displaced 20 meters in 4.7 seconds. which piece of information is missing for the correct calculation of velocity? the starting point the direction the end point the time per meter

Direction is missing.

Explanation:

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds.

We know that velocity is a vector quantity. It has both magnitude as well as direction. Velocity is defined as the total distance per unit time i.e.

i.e. the magnitude of velocity is 4.3 m/s

Here, only velocity is given but its direction is missing. So, the missing information is " the direction ".
