The time needed by the bike to reach the final velocity is 3 .75 seconds ,Option C is the write answer.

<h3>What is Velocity ?</h3>

It is defined as the distance covered by an object in a given amount of time. It is a vector quantity , its unit is m/s , km/hr etc.

It is given in the question that

Initial Velocity = 20m/s

Final Velocity = 35m/s

Acceleration = 4m/sq.s

Time = ?

The equation of motion

v = u +at will be used

35 = 20 + 4 * t

15 = 4* t

t = 3.75 seconds

Therefore the time needed by the bike to reach the final velocity is 3 .75 seconds.
