Question

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

Answer 1

Answer:

Distance traveled/ time taken to travel this distance) =9/1 =9 km/ hr. Similarly, the distance traveled by Akhtar in one hour is 12 km. So, the speed of Akhtar =( Distance traveled/ time taken to travel this distance) =12/1 =12 km/ hr.

Answer 2

$speed = \frac{distance}{time}$

time is 1 hr for both

ratio of 2 speeds =

$\frac{speed1}{speed2} = \frac{\frac{9}{1} }{\frac{12}{1} } = \frac{9}{12} = \frac{3}{4}$

ie 3:4 is the ratio of their speeds
