    d = 400 m t = 14.5 min 14 min 30 sec total time will be = 870 sec it will take him to complete one track = 108.75 sec so velocity obtained per track will be v = d/t v = 400 /108.75 v = 3.7 m /s

    @leon549 They don't really learn a lot if you're just making th equestion instead of helping them step by step.

    average velocity is the displacement of a an object per unit time. displacment is the difference in the initial and final position in the given interval of time in which the average velocity has to be measured

    After 8 complete laps he is back where he started. Be sure you know the difference between average speed, and average velocity.

    @leon549 as @thomasker says: They learn little by being given the answer, and even less when it is not correct
