Question: how to calculate the distance travelled by a car?
Answer: For example, a car travels 400 miles in seven hours and you want to know how fast, on average, the car traveled. Using the equation s = d ÷ t, plug in the distance of 400 miles for d and time of seven hours in for t: s = 400 miles ÷ 7 hours = 57.1 miles/hour.
