A material point moves along a straight path such that in 2 s it moves from an initial position SA = +0.5 m to a position SB = -1.5 m. Then, in 4 s it moves from the SB position to SC = +2.5 m. With that we will have that the average speed and the average speed of travel of the material point during the time interval 6 s are,

Question
A material point moves along a straight path such that in 2 s it moves from an initial position SA = +0.5 m to a position SB = -1.5 m. Then, in 4 s it moves from the SB position to SC = +2.5 m. With that we will have that the average speed and the average speed of travel of the material point during the time interval 6 s are, respectively:
Choose one:
a. 1 m / s and 0.333 m / s
B. 0.333 m / s and 1 m / s
c. both equal to 1 m / s
d. 0.4 m / s and 2 m / s
e. 2 m / s and 0.4 m / s
