Which of the following is the correct formula for calculating speed?
distance divided by mass
mass divided by volume
time divided by distance
distance divided by time

The formula used to calculate speed is distance divided by time.

Explanation:

Speed is defined as the rate of change of distance with respect to time.

The equation used to calculate speed of the object follows:

The S.I. unit of speed is meters per second (m/s)

For Example: A car traveled a distance of 200 meters in 5 second.

Hence, the formula used to calculate speed is distance divided by time.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
