The equation that relates the time, t, it takes to travel a given distance, d is d = rt
<h3>What is Speed?</h3>
This is a scalar quantity and can be defined as the magnitude of the rate of change of its position with time.
d = rt
where d is distance, r is speed or rate, t is time.
We can calculate the time by dividing the distance with the rate (speed).
t = d/r
This is why it was chosen as the most appropriate choice.
