If you have a car travel 400m in 20 seconds how fast is it going using the chart distance over time

After looking around, I really can't find any chart.  But you told me the distance covered and the time it takes to cover the distance, so I can calculate the speed by using a pretty simple formula ... it's actually the definition of speed, and it'll be useful to you if you memorize it:

Speed = (distance covered) divided by (time to cover the distance) .

With the numbers you gave in your question ...

Speed = (400 meters) / (20 seconds)

Speed = 20 meters/second

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
