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

$\large{\bold{\underline{Solution:}}}$


We know that, Speed = $\bold{\frac{Distance}{Time} }$

Speed of Hamid$\bold{= \frac{9 \: km}{1 \: h} = 9 \: km/h}$

Speed of Akhtar$\bold{= \frac{12 \: km}{1 \: h} = 12 \: km/h}$

Ratio of speed of Hamid to that of speed of Akhtar = $\bold{\frac{9}{12} = \frac{3}{4} =}$$\bold{\fbox{\red{3 : 4}}}$

Answer 2

Answer:

3:4

Step-by-step explanation:

The distance traveled by Hamid in one hour is 9 km.

So, the speed of Hamid =( 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.

Therefore, the ratio of the speed of Hamid to the speed of Akhtar is

9:12 or, 3:4 (Answer)
