Your teacher oftentimes ridess a bicycle. one day, he biked 500 meters from his house to his distination for only 500 s. what was your teacher's average velocity

In this question there are all the required information's. Using those information's the answer to the question can be easily found. It is given that the teacher travels for 500 meters within a time of 500 seconds. Now we have to find the average velocity at which the teacher covered the distance.
We already know that
Average Velocity = Distance traveled/ Time taken
Now we can put all the given information's in this equation and get the required answer.
Average Velocity = 500/500 meter/second
                           = 1 m/s
So the teacher travels at an average velocity of 1m/s.
