Question

Which formula correctly shows how to calculate the time taken, given the

average velocity and the displacement of an object?
O A time = velocity / displacement
OB) time = velocity * displacement
OC) time = displacement / velocity
OD) time = displacement + velocity
D​

Answer 1

A time = velocity / displacement

Answer 2

Given the average velocity and the displacement of an object, the time taken is
`time=(displacement)/(velocity)` (option c)

Step-by-step explanation:

Speed ​​is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, velocity is a quantity that expresses the variation in position of an object and as a function of time. Velocity also considers the direction and direction in which an object's displacement occurs, so it is considered a vector quantity.

The speed is expressed as:

`velocity=(displacement)/(time)`

So the units to define the speed are in distance parameters (meters, centimeters, kilometers) and in variables related to time (seconds, minutes). Its unit of measurement in the International System (S.I.) is the meter per second
`(m)/(s)`

Given the average velocity and displacement of an object, time can be obtained from the definition of velocity:

`velocity=(displacement)/(time)` ⇒ displacement=velocity*time ⇒
`time=(displacement)/(velocity)`

Given the average velocity and the displacement of an object, the time taken is
`time=(displacement)/(velocity)` (option c)
