Welcome to PF,

The two pieces of information you have been given are the distance travelled by the cyclist and the time it took him to do so. Can you think of how you might use the given information to calculate what the problem is asking for? As a starting point, what is the definition of average velocity?

average velocity = Displacement divided by time

so do i convert km into m and min into secs?

You need to use conversion factors and dimensional analysis.
1 km = 1000 m and 1 min = 60 s

Change these into a form so that the kms and mins cancel out when you multiply them with the average velocity, and then you will get the answer in m/s.
