I don't understand how to find the distance that robot travels in 10s.
 
Mathematics news on Phys.org
t=0 to t=2 … the robot moves away from its starting position 2.56m

t=2 to t=5 … the robot moves back toward its starting position 0.81m

t=5 to t=8 … the robot moves away again from its starting position 0.81m

t=8 to t=10 … the robot moves back to its starting position 2.56m

total distance traveled by the robot would be … ?
