Georgia is jogging with a velocity of 4 m/s when she accelerates at 2 m/s2 for 3 seconds. How fast is Georgia running now?

Georgia is moving by uniformly accelerated motion, with initial velocity

v_0 =4 m/s
and with constant acceleration of

a=2 m/s^2
so her velocity at time t is given by

v(t) = v_0 + at = 4 m/s + (2 m/s^2)(3 s)= 10 m/s
So now Georgia is running at 10 m/s.
