Answer:

Step-by-step explanation:
Given
initial velocity of bicycle,

velocity of the bicycle after the first phase of acceleration,

duration of first phase of uniform acceleration,

duration of second phase of zero acceleration,

uniform velocity during the second phase,

duration third phase of uniform deceleration,

final velocity after the third phase of motion,

- Now we find the acceleration in the first phase of motion:


Now using the equation of motion:


is the distance covered in the first phase of motion.
- Distance covered in the third phase of motion:



- Now we find the deceleration in the third phase of motion:



Now using the equation of motion:


is the distance covered in the third phase of motion.
Hence the total distance covered by the bicycle in the whole incident is:
