From the information provided, the velocity after 2 seconds is 11 m/s.
From the equations of motion;
v = u + at
Where;
v = final velocity
a = acceleration
t = time taken
The initial velocity of the bike was 7 m/s and its acceleration is 2 m/s2. This change occurred within a time of 2 seconds.
Hence;
v = 7 + 2(2)
v = 11 m/s
The velocity after 2 seconds is 11 m/s.
