Rate, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.

Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Speed is calculated by dividing the distance traveled by time. It does not have direction. Average velocity is the displacement (change in position) divided by time.
How the choice of reference frame is related to speed and velocity measurements.
The difference between vectors and scalars. Introduction to distance, displacement, speed, and velocity.
