Explanation
To calculate the average speed of the car, the formula used is distance divided by time. From the information given in the question, it is known that the car travelled a distance of 0.6m (the distance between the road marks) in a time of 0.5 seconds (time between photo 1 and photo 2). All we have to do is to plug these values into the formula to obtain the average speed:Speed = Distance / Time = 0.6m / 0.5s
