the figure below shows the movement of a pedestrian from point b to point e. using the graph, answer the following questions:

a) what is the speed of the pedestrian?

b) after what time since the stop did he arrive at point e?

c) write the formulas for function d(t) for sections bc, cd, and de

A.

from the question,

the total speed for the pedestrian is

40km and the total time is 10hr

substitute them in the formula, we get

speed = 4km/hr

B. 10hrs - 6hrs = 4hours

C. BC is deacceleration = -dv/dt

CD is constant acceleration = dt = 0

the answer is the third / last answer
