Asked by yoo
A car drives down a road in such a way that its velocity ( in m/s) at time t (seconds) is
v(t)=2t^1/2 +2 .
Find the car's average velocity (in m/s) between t=4 and t=9.
i really need help with thisss

V(4) = 2 * sqrt(4) + 2 = 4 + 2 = 6m/s.
V(9) = 2 * sqrt(9) + 2 = 6 + 2 = 8.
V(avg.) = (6 + 8) / 2 = 7m/s.
V(9) = 2 * sqrt(9) + 2 = 6 + 2 = 8.
V(avg.) = (6 + 8) / 2 = 7m/s.
