Your motion along the x-axis begins at rest and at x= 0. The motion consists of acceleration at 2.00 m/s2for 10.0 s, a time period of 6.00 seconds with no acceleration, and then deceleration at -1.00 m/s2for 20.0 s resulting in a final speed of zero. The total distance traveled is 420 m. What is the average speed during this motion? Give answer to 3 significant figures.
