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
Answer:
37 degrees
Step-by-step explanation:
Tan x = 4.8/6.3
Tan x = 0.76
Tan^-1 (0.76) = 37 degrees
