We know that,

The speed of an object is the distance travelled by it in an hour.

Now,

It is given in the question that,

Distance travelled by Hamid in 1 hour = 9 km

Also,

Distance travelled by Akhtar in 1 hour = 12 km

Therefore,

Speed of Hamid = 9 km/h

Also,

Speed of Akhtar = 12 km/h

Hence,

We can calculate the ratio of speed of Hamid to the speed of Akhtar as follows:

=

=

=
