Distances travelled by Hamid and Akhtar in an hour are $ 9 \mathrm{~km} $ and $ 12 \mathrm{~km} $. Find the ratio of speed of Hamid to the speed of Akhtar.
Given:
Distances travelled by Hamid and Akhtar in an hour are $9\ km$ and $12\ km$ respectively.
To do:
We have to find the ratio of the speed of Hamid to the speed of Akhtar.
Solution:
The distance travelled by Hamid in one hour $=9\ km$
The distance travelled by Akthar in one hour $= 12\ km$
We know that,
Speed is defined as the distance travelled by an object in an hour.
Therefore,
The speed of Hamid$=9\ km\ per\ hr$
The speed of Akthar $=12\ km\ per\ hr$
The ratio of the speed of Hamid to the speed of Akthar $ =9 : 12$
$ =3 : 4$
The ratio of the speed of Hamid to the speed of Akthar is $3 :4$.
