A person is walking briskly in a straight line. The figure shows a graph of the person’s position as a function of time . What is the person’s average velocity between t = 6 s and t = 10 s? will give brainliest

Distance travelled = 6 - 2.7= 3.3 and time = 10 - 6 =- 4
Average speed = 3.3 / 4 = 0.8 ms-1
