Distances travelled by Hamid and Akhtar in an hour are 9 km and 12 km. Find the ratio of speed of Hamid to the speed of Akhtar.

Explanation

Given,

Distance travelled by Hamid in an hour `= 9 km`

and distance travelled by Akhtar in an hour `= 12 km`

Again we know Speed = Distance / Time Taken

So, Speed of Hamid `= (9km)/(hr)`

And, speed of Akhtar` = (12km)/(hr)`

Therefore,the ratio of the speed of Hamid to the speed of Akhtar
= Speed of Hamid: Speed of Akhtar `= 9:12`

Thus, the ratio of the speed of Hamid to the speed of Akhtar` = 3:4`
