If you walked 29752 meters in 2.00 hours what would your average speed be in m/s. then, suppose you slow down to 3.00 m/s at the midpoint, but then pick up again and accelerate to the speed calculated before. it takes you 30.0 s to accelerate. find the magnitude of the average acceleration during this time interval
