There are several information's of immense importance already given in the question. Based on the given information's the answer to the question can easily be determined.
Distance covered by the bicycle = 5000 meter
Time taken by the bicycle to reach the distance = 500 second.
Velocity of the bicycle = Distance / Time taken
= 5000/500 meter/second
= 50 meter/second
So the velocity of the bicycle is 50 meter per second. I hope the procedure is clear enough for you to understand. In future you can always use this procedure for solving similar problems.
1. Scientists are responsible for removing plasmids, small rings of DNA, from bacterial cells.
2. The Enzymes cut open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome.
3. The human insulin gene attaches the open ends of the plasmid to form a closed ring.
4. Some bacterial cells take up the plasmids that have the insulin gene.

5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.</span>

The resultant velocity is 360.81 m/s and the velocity of the dolphin swims is 11 m/s
Explanation:
The boat travelling is 13.4 m/s
The captain walks on the deck is 1.3 m/s
The resultant velocity = a² + b² = c²
= 13.4² + 1.3²
= 179.56 + 1.69
c² = 
c= 360.81 m/s
To find the velocity, the dolphin swims in 55 m and the acceleration is 5.0 s
velocity = distance / acceleration
= 
= 11 m/s
Therefore, the velocity is 11 m/s.
